Grissom Air Reserve Base

Grissom Air Reserve Base is a United States Air Force base, located about 12 mi north of Kokomo in Cass and Miami counties in Indiana. The facility was established as a U.S. Navy installation, Naval Air Station Bunker Hill, in 1942 and was an active Air Force installation, Bunker Hill Air Force Base from 1954 to 1968, and Grissom Air Force Base from 1968 to 1994. Pursuant to a BRAC 1991 decision, the installation was downsized to an Air Force Reserve installation and renamed Grissom Air Reserve Base.

Since then it has been a joint-use civil airport/military base. Approximately 1700 acres plus the runway and taxiways comprise the current military installation, with the Grissom Aeroplex comprising the civilian aviation activities providing general aviation and charter service.

Originally named Bunker Hill Air Force Base, the base was renamed Grissom Air Force Base in 1968 in memory of astronaut and Indiana native Lieutenant Colonel Virgil I. "Gus" Grissom, USAF, who, along with fellow astronauts Lieutenant Colonel Ed White, USAF, and Lieutenant Commander Roger Chaffee, USN, perished in the Apollo 1 fire at Cape Canaveral Air Force Station Launch Complex 34 on 27 January 1967.

It is home to the largest KC-135R Stratotanker wing in the Air Force Reserve Command (AFRC), plus units from the United States Army Reserve and also the US Marine Corps Reserve. The host unit is the 434th Air Refueling Wing (434 ARW), the "Hoosier Wing", which consists of three major groups and a variety of squadrons and flights. The wing develops and maintains the operational capability of its units and trains reservists for worldwide duty, with the wing operationally-gained by the Air Mobility Command (AMC). Training consists of flight operations, deployments, and weekday and weekend training.

Other organizations located at Grissom ARB include the U.S. Army Reserve's Company A, 1st Battalion, 330th Regiment; 316th Psychological Operations Company (Tactical); Detachment 1, 855th Quartermaster Company; the U.S. Marine Corps Reserve's Marine Corps Reserve Center Grissom and Detachment 1, Communications Company, 4th Marine Logistics Group.

Background
On 18 March 1942, the Bureau of Yards and Docks (BuDocks) sent out a letter to the Judge Advocate General of the Navy (JAG), Rear Admiral Walter Browne Woodson, for the acquisition of land near Peru, Indiana, with the intention of constructing a Naval Reserve Aviation Base. The following day, the Shore Station Development Board sent a letter of recommendation to the US Secretary of the Navy (SECNAV), Frank Knox, estimating the cost of the project, including land acquisition, at $7,000,000. On 21 March 1942, the Chief of Naval Operations, Fleet Admiral Ernest King, concurred with BuDocks and also sent a letter to SECNAV. Secretary Knox sent a letter the same day to JAG Woodson approving the base.

On 27 March 1942, Russell B. Moore Company, Indianapolis, Indiana, signed contract NOy-5485, for the architectural and engineering services for Naval Reserve Aviation Base at Peru, Indiana. Two other firms had been considered; Walter W. Ahlschlager & Associates, Chicago, Illinois, and Phelps & Peck, Michigan City, Indiana.

On 3 April 1942, contract NOy-5475, for the construction of a Naval Reserve Aviation Base at Peru, Indiana, with Captain R.D. Spalding, USN, the Officer-in-Charge, was sent out. The contract included Projects 1 to 47, with a fee of $4,965,500. Changes "A" through "M", were added over the next several months, adding Projects 48 to 77, and 501, and on 19 November 1942, Purchase Order 4057 authorized Projects 78 to 87, with manual instruction authorizing Project 88.

Four contractors were considered for the project; James T. Barnes Construction Company, Logansport, Indiana; Sollitt Construction Company, Inc., South Bend; William P Jungclaus Company, Indianapolis; and a joint venture between J.L. Simmons Company, Inc., Indianapolis, and United Construction Company, Winona, Minnesota. The bid was given to J.L. Simmons Company, Inc. and United Construction Company, and signed on 16 April 1942.

Construction
Preliminary plans for the base were issued 20 April 1942. The base was commissioned on 1 July 1942, with a contingent of Naval personnel moving in on 15 July 1942. Actual construction wasn't finished until 12 April 1943, with 99.5% field work completed. The final cost was $13,064,424.43.

The design called for a Naval Air Station, occupying 2158 acre, with the facilities and equipment to house and train 1,200 naval aviation cadets. This would include the housing and other necessary facilities needed for a total of 3,200 officers and men. Station facilities would include four runways of 5000 ft long and 200 ft wide; a square landing mat with sides 2500 ft long (6250000 sqft); taxiways, warm-up aprons, and approaches; 77 buildings with 853917 sqft of floor space, water supply, heating; and sewage disposal plants; 8.5 mi of paved streets and 5 mi of sidewalks. The training facilities included 25 auxiliary fields, within a 20 mi radius, with a combined area of 4696 acres.

Of the 2,158 acres, approximately 75 acre were of dense timber that needed to be cleared. Other obstructions included, houses, barns, boulders, and county and state roads. The main base was, and still is, located approximately 9 mi south of Peru, Indiana, on US Route 31; 18 mi north of Kokomo; Logansport 20 mi to the northwest; and Wabash 20 mi to the northeast. Indianapolis, Indiana's capitol, is 64 mi south; Fort Wayne 64 mi northeast, South Bend 70 mi north, and Chicago 125 mi northwest.

The Site Selection Board selected this site because it was centrally located with ready accessibility from several large cities. The land is level for miles around, which afforded many possibilities for auxiliary fields. It was out of the flight routes of commercial airlines. The soil type was satisfactory with gravel being locally available for concrete. It could be serviced by the Pennsylvania Railroad, with a station only 1.5 mi away and construction of a switch track easily possible; also paved highways and bus lines nearby. Electrical power available from Peru. Satisfactory climate conditions, as indicated by Weather Bureau Reports. Water treatment for the steam boilers seemed to be the only draw back.

Upon receiving the Letter of Intent on 28 March 1942, Russell B. Moore Company established a temporary headquarters and moved personnel and necessary drafting, surveying and office equipment and supplies to an old schoolhouse at Bunker Hill, which they occupied until completion of the Construction Engineering Office on the site 13 May 1942. Surveying the site started 1 April 1942. J.L. Simmons Company, Inc. and United Construction Company received their Letter of Intent 4 April 1942, and immediately began moving equipment in to clear the site, including removal of buildings, trees, and grading as soon as elevations for the finished grade had been determined. Temporary structures were built, including a cement warehouse, a large general warehouse, 200 ×, time office, a large number of movable, built on skids for easy removal, tool storage sheds and small storehouses. All construction material was delivered by truck until the completion of the spur track on 10 June 1942, after which a large portion of the construction material came in by rail. Peak days of traffic volume were as follows: 129 freight carloads of paving material received via the spur track on 30 October 1942, and 1755 truck loads of paving material received on 25 October 1942.

In addition to the previously mentioned builds, a combined saw mill and carpenter shop was constructed, and equipped with wood working machinery. A temporary building was built and equipped as a restaurant, in which lunches were served to all persons on site at a moderate cost. A combination garage and repair shop was constructed and equipped to keep equipment in operating condition. A first aid building, staffed by two nurses was built. Night lighting, so paving operations could continue at night, was provided by electric floodlights. One large diesel powered permanent type generator with overhead distribution wiring, and several portable gasoline powered generators produced the electricity.

Many of the buildings utilized standard BuDocks plans and specifications for standard air station buildings. Specialized buildings were designed by the Moore Company. Most of the buildings were of a light, temporary type, designed to only be used for a limited time.

The safety record during construction was: one serious fire at Subsistence Building 26, 4,043 first aid cases, with 465 of those needing services of a physician. On the night of 3 August 1942, building 26 caught fire while it was about 90% complete, damage was estimated at 53% of its value.

Due to cost overruns, some of the projects were moved to contracts NOy 5938 and NOy 5958.

Runways and warming-up platforms
Initially the four runways were to be 3600 ft long and constructed of macadam with asphalt topping, along with the landing mat. On 30 October 1942, Change "G", ordered the runways lengthened to 5000 ft, and to now be constructed of concrete. Each runway was 8 in thick and not reinforced. The runways ran northeast to southwest, northwest to southeast, east to west, and north to south. Lights were located every 400 ft along the length of three runways, with the northwest to southeast runway being spaced at 200 ft intervals. The ends of the runways were separately marked with two, three, four, and five lights. There was a temporary 2000 sqft landing field built for official visits during construction of the base.

The Warming-up Platform consisted of 8 in thick unreinforced concrete lanes 20 ×, with a total area of 209940 sqyd, with 2800 steel mooring eyes located in the concrete.

The building was equipped with four oil fired steam generating boilers, each able to 13500 lbs of steam per hour at 100 psi pressure, and the additional equipment needed, oil burners, pumps, and water heaters. The building also contained three secondary concrete fuel oil storage tanks with a capacity of 25000 usgal that were connected to the main 275000 usgal storage tank. Structures 16 and 43 were for fuel oil storage. Fuel oil would be unloaded at the fuel oil transfer house, building 43, a 16 ft×14 ft, reinforced concrete building, from railroad tank cars. Three tank cars could be unload simultaneously, the oil being pumped to a 275,000 gal. pre-stressed reinforced concrete storage tank, building 16, 72 ft diameter and 10 ft high tank buried 4 ft below grade and covered with earth. A small gauge and apparatus room adjoined the tank. Oil flowed by gravity from the tank to the heating plant in steam heated pipes to prevent coagulation. With the exception of a few buildings equipped with separate boilers, all buildings on Station were supplied with 100 psi of steam through a 38000 ft welded underground steam distribution supply and return mains. The steam was used for both heating and hot water heating.

Buildings 48–1 through 48–5 were transformer houses. The city of Peru provided a 33,000 volt transmission line that fed a sub-station at the northeast corner of the base. The sub-station had three 500KVA step down transformers that took the voltage from 33,000 volt, 3 phase, 3 wire to 12,500 volt, 3 phase, 4 wire. Primary distribution was then by aerial or underground transmission to secondary distribution locations. There were 4.35 mi of overhead line, with 17 mi of bare copper wire; and 4 mi of underground line, with 13 mi of lead covered cable, 15.5 mi of fiber conduit encased in concrete and 58 manholes. To further step down the voltage for use in buildings, 18 transformer banks were utilized, with 67 oil insulated, air cooled transformers in transformer vaults and transformer houses, with a total capacity of 3,119 KVA volts. Standby emergency electricity was supplied by two 175 kW generators connected to two 12 cylinder gasoline engines.

Building 40 was the Fire Station. This was a one-story, rectangular building, 92 ×. It had an apparatus room, office, toilets, dormitory, and a hose tower that was 8 × by 37 ft tall.

The well houses had pumps capable of 350 U.S.gal/min that transferred the water through an 8 in line to the treatment plant, building 21. Building 21 was a partial two-story reinforced concrete building adjoining an underground 450000 usgal concrete emergency reservoir for treated water. The building contained electric motor driven pumps, tanks, chlorinators, dry chemical feeders, and filters for purifying and softening the water. 6 mi of cast iron pipe, 2 to 10 in diameter, distributed the water under 45 psi pressure to 46 fire hydrants and 2,405 water fixtures on the station.

Structures 19A–D were for gasoline storage and distribution. Delivered by tank car at four unloading points on a special railroad siding, and by gasoline trucks at four additional points, the gasoline was stored in four underground pre-stressed reinforced concrete tanks that were lined with Thiokol. Three of the tanks had 50000 usgal capacity and were used for 73 octane gasoline. The other was a 25000 usgal tank used for 100 octane gasoline. The fuel was pumped to distribution points through two separate piping systems, one for 73 octane and one for 100 octane, by two submerged type multiple stage centrifugal, 200 U.S.gal/min, pumps at each tank; each pump powered with a 15 hp electric motor. Distribution points for 73 octane gasoline consisted of a tank truck filling stand, 200 gpm, and 56 gasoline servicing pits for fuelling planes directly, located at the warmup aprons, with capacity to fuel 48 planes simultaneously at the rate of 25 U.S.gal/min per plane. The 100 octane gasoline, the tank truck filling stand was capable of 300 U.S.gal/min, and four planes could be fueled at a rate of 100 U.S.gal/min. The system included 2.7 mi of 1 to 12 in diameter welded steel pipe. The 100 octane system was actually used for 87 octane gasoline with 100 octane being provided by a later contract.

A main railroad spur, 9928 ft long, connected the station to the Pennsylvania Railroad under a revocable agreement. Additional spurs for unloading gasoline branched off the main with an additional 4236 ft of track.

World War II Navy service
Naval Reserve Air Base Peru, as the base was named when commissioned, was built to train United States Navy, United States Marine Corps and United States Coast Guard pilots. The base would go through several names just during WWII. On 1 January 1943, the name was changed to Naval Air Station Peru (NAS Peru), and only three months later on 1 March 1943, the name changed again, this time to Naval Air Station Bunker Hill (NAS Bunker Hill), which it kept for the rest of the war.

Pilots would study for 12 weeks in a pre-flight school, then transfer to Bunker Hill for an additional 12 weeks of flight training, after which, they would transfer to intermediate aviation training stations such as Naval Air Station Pensacola. During the course of their training at Bunker Hill cadets would study celestial and dead-reckoning navigation, radio communication, care and repair of engines, physical fitness training that included boxing, wrestling, hand-to-hand fighting, and swimming. The base trained 5,997 American Naval Aviation Cadets, of which 4,568 qualified to advance to Intermediate Flight Training, while 854 were sent to Naval Station Great Lakes for reclassification. In addition to the American cadets, Bunker Hill trained 701 British Royal Navy cadets.

By 31 March 1945, there were 407 N2S-3 Kaydet trainers, nearly one-quarter of the U.S. Navy's inventory.

One of the most famous alumni of Bunker Hill was former major league baseball player Ted Williams. He received training as a Marine Corps Naval Aviator at NAS Bunker Hill.

After World War II the base area reverted to farming use, with a civilian crew of government caretakers maintaining the military buildings.

Transfer to the United States Air Force
The United States Air Force obtained right of entry to 25 buildings from United States Navy on 16 November 1951, and used the base under United States Air Force Storage Branch. Still in inactive status, it was transferred from the Navy to the Air Force on 31 March 1954.

323d Fighter-Bomber Wing and 319th Fighter-Interceptor Squadron
In the wake of the Korean War, the Air Force reopened the installation as Bunker Hill Air Force Base on 22 June 1954, and assigned it to Tactical Air Command. The base began to host the 4433d Air Base Squadron and the 323d Fighter-Bomber Wing and the 323d Air Base Group coming under TAC's Ninth Air Force. Initially training with North American F-86Fs, these were quickly upgraded to the North American F-86H Sabre and then to the North American F-100A/D in 1956 to become proficient in tactical air operations. The wing's aircraft wore a band on the tail, and around the nose edged with small black checkers. In 1955, the 319th Fighter Interceptor Training Squadron of the Air Defense Command joined forces at the base, reporting to the 4706th Air Defense Wing at K. I. Sawyer AFB, Michigan. Initially operating the F-89 Scorpion interceptor, the mission of the 319th FIS was the air defense of the southern Great Lakes and Chicago-Gary-Central Indiana region. It was later upgraded to the F-94 Starfire. The ADC interceptors remained until 1 January 1959.

Strategic Air Command
Strategic Air Command (SAC) assumed operational control of Bunker Hill Air Force Base from Tactical Air Command on 1 September 1957, with the 8th Air Force assuming jurisdiction of the base; the Air Force then inactivated the 323d Fighter-Bomber Wing, and the 4041st Air Base Group arrived that day. The Air Force began to station the new Boeing KC-135A Stratotanker on the base in 1957.

305th Bombardment Wing, Medium


On 1 June 1959, Strategic Air Command moved the 305th Bombardment Wing, Medium, (305 BMW) from MacDill Air Force Base in Florida to Bunker Hill Air Force Base. At the time, the wing flew the Boeing B-47 Stratojet; later, the supersonic Convair B-58 Hustler began replacing the B-47s. Starting in 1960, the Air Force equipped the 319th Fighter-Interceptor Squadron with the F-106 Delta Dart until the squadron departed on 1 March 1963.

Nuclear accident
On 8 December 1964, a B-58 carrying five nuclear weapons, including a 9-megaton thermonuclear bomb, slid off an icy runway and caught fire during a training mission. While taxiing it was caught in the jet blast from the aircraft in front of it while turning onto the runway and applying power of its own. This caused the bomber to lose control and slide off the left hand side of the taxiway. The left main landing gear passed over a flush mounted taxiway light fixture, 10 ft further the landing gear grazed the left edge of a concrete light base. After traveling another 10 ft the left main landing gear struck an electrical manhole box which caused it to collapse, rupturing a fuel tank. The aircraft then caught fire.

The aircraft commander, Leary Johnson, and defensive system operator, Roger Hall, were able to escape with minor injuries. However, the navigator, Manuel "Rocky" Cervantes, ejected in his escape capsule, which landed 548 ft from the bomber; he did not survive. The five nuclear weapons on board were burned, causing contamination of the crash area. The Air Force claimed that the crash site was cleaned of contamination, however, it was discovered that the aircraft and some of the soil from the area were only removed to another site on the base and reburied. The burned bombs were shipped to Atomic Energy Commission facilities at Clarksville, Tennessee, Medina Base, Texas, Rocky Flats, Colorado, Miamisburg, Ohio, and Oak Ridge, Tennessee, where it was determined that none of the plutonium from the weapons was released. A 1996 survey found that the area of the crash were still contaminated and required further remediation of the site.

Apollo 1 disaster – renaming base
On 27 January 1967, the cabin of the Apollo 1 spacecraft caught fire during a pre-launch preparation at Cape Canaveral Air Force Station Launch Complex 34, killing United States Air Force astronaut Lieutenant Colonel Virgil I. "Gus" Grissom, a Mitchell, Indiana, native and Purdue University graduate. The Air Force officially renamed Bunker Hill Air Force Base as Grissom Air Force Base in his honor on 12 May 1968.

305th Air Refueling Wing
With the retirement of the B-58 in 1970, the Air Force redesignated the 305th Bombardment Wing, Medium, as the 305th Air Refueling Wing (305 ARW) on 1 January 1970. The Air Force transferred the 70th Air Refueling Squadron from another wing at Little Rock Air Force Base to the 305th Air Refueling Wing in 1970. From the early 1970s, the 305th Air Refueling Wing deployed KC-135 aircraft to Europe, Alaska, Greenland, and the Pacific to support worldwide tanker task forces. Meanwhile, with the closing of Bakalar Air Force Base, near Columbus, the 931st Air Refueling Wing arrived on 15 January 1970.

In June 1972, the 305th Air Refueling Squadron deployed elements to Korat Air Base, Thailand, as the 4104th Air Refueling Squadron (Provisional). Later in 1972 the 4104th ARS (P) was relocated to U-Tapao Royal Thai Navy Airfield.

Combined active duty and reserve operations
The Air Force Reserve joined the Grissom personnel complement in the early 1970s with the activation of the 434th Special Operations Wing (434 SOW) and their Cessna A-37 Dragonfly aircraft to the base on 15 January 1971. On 1 October 1973, the Air Force Reserve redesignated the 434th Special Operations Wing as the 434th Tactical Fighter Wing, with the 434th later transitioning from the A-37 to the A-10 Thunderbolt II as the latter aircraft entered the USAF inventory..

In 1975, the Air Force inactivated the 3d Post Attack Command and Control System of the 305th Air Refueling Wing and transferred specialized Boeing EC-135s to the 70th Air Refueling Squadron of the 305th Air Refueling Wing. The 931st Air Refueling Group (931 ARG) departed on 1 July 1975. The United States Army Reserve began its presence at Grissom in the 1970s.

On 1 February 1978, the Air Force renamed the 305th Air Refueling Wing as the 305th Air Refueling Wing, Heavy. The Air Force activated the 931st Air Refueling Group at the base on 1 July 1978 as the second group of Air Force Reservists. The base also served as the home of one active duty wing and two reserve wings, using 60 KC-135 Stratotanker and 18 A-10 Thunderbolt II fighter aircraft. The 72d Air Refueling Squadron of the Air Force Reserve began operating its KC-135 Stratotanker aircraft from Grissom in 1978.

The 305th Air Refueling Wing, Heavy, provided tanker refueling support to units involved in the invasion of Grenada in October 1983. The 931st Air Refueling Group departed Grissom on 1 July 1987. The Air Force Reserve on 1 July 1978 redesignated the 434th Tactical Fighter Wing as the 434th Air Refueling Wing, Heavy, giving it a similar mission to that of the 305th Air Refueling Wing, Heavy.

The 305th Air Refueling Wing, Heavy, provided tanker support to units involved in the United States invasion of Panama in December 1989. From August 1990 to June 1991, deployed 305th Air Refueling Wing, Heavy, personnel and aircraft provided refueling support for air operations in southwest Asia as part of Operation Desert Storm. The 305th Air Refueling Wing, Heavy, also delivered food to the Kurds in Northern Iraq from April to May 1991. The Air Force redesignated the wing as 305th Air Refueling Wing on 1 September 1991.

The end of the Cold War led to a downsizing of the military. The Base Realignment and Closure Commission of 1991 recommended closure of Grissom Air Force Base. On 1 February 1992, the Air Force Reserve redesignated the 434th Air Refueling Wing, Heavy, as the 434th Air Refueling Wing and that year activated the 74th Air Refueling Squadron within the 434th Air Refueling Wing to operate the KC-135 Stratotanker. The Air Force inactivated Strategic Air Command (SAC) and realigned the 305th Air Refueling Wing to the newly established Air Mobility Command (AMC) on 15 June 1992. The Air Mobility Command merged air refueling aircraft from Strategic Air Command with strategic airlift aircraft (e.g., C-5, C-141 and tactical theater airlift aircraft (e.g., C-130) from the concurrently disestablishing Military Airlift Command (MAC). The Air Force Reserve renamed the 434th Air Refueling Wing as the 434th Wing on 1 August 1992. The Base Realignment and Closure Commission of 1993 directed realignment of Grissom Air Force Base to the Air Force Reserve (AFRES).

The 305th Air Refueling Wing phased out operations and ended its presence on base on 30 September 1994, when the Air Force inactivated it. The Air Force then immediately reactivated a new 305th Air Refueling Wing with different personnel and equipment at McGuire Air Force Base in New Jersey. The Air Force inactivated the KC-135Rs of the 70th Air Refueling Squadron of the 305th Air Refueling Wing; this squadron transferred to Travis Air Force Base in California, joined another wing, and used a different aircraft. The Air Force also retired the Boeing EC-135G/L radio relay aircraft as part of the demise of the Post Attack Command and Control System.

Air Force Reserve era
Effective 1 October 1994, Grissom Air Force Base ceased active-duty operations, and the active Air Force transferred nearly half of the former base, including the runway, to the Air Force Reserve as Grissom Air Reserve Base. The Air Force Reserve (AFRES) redesignated the 434th Wing as the 434th Air Refueling Wing (434 ARW), and activated the 434th Mission Support Group. The 434th Air Refueling Wing operates two KC-135 Stratotanker air refueling squadrons, operationally within the Air Mobility Command (AMC).

Because of the inactivation of the installation's active duty KC-135 wing due to BRAC, the Air Force reassigned Grissom Air Force Base in 1994 to the Air Force Reserve which later became the Air Force Reserve Command (AFRC) in 1997. The base added Marine Corps Reserve units in 2001 and United States Navy Reserve units in 2002. In 2005, in an effort to consolidate Navy Reserve activities and units, the Navy Reserve transferred all its Grissom units to the Navy Operational Support Center at Heslar Naval Armory in Indianapolis, Indiana.

In 2008, Grissom Air Reserve Base entered into a joint-use agreement and opened its runway to civilian operations. Miami County Aviation manages the day-to-day civil operations at Grissom Air Reserve Base. The extremely long runway and instrument navigation facilities make Grissom Air Reserve Base especially well suited to business jets as a refueling stop for long cross-country flights. Civilian air traffic controllers also staff a radar approach control facility at the airport.

Until the retirement of the Space Shuttle on 21 July 2011, Grissom was also listed as one of the emergency landing sites due to its 12,500-foot runway.

In 2015, it was announced that the Grissom was in the running for a squadron of the new KC-46A Pegasus. In October, it was announced that the base would not be receiving the aircraft, which instead was allocated to the 916th Air Refueling Wing at Seymour Johnson Air Force Base. Grissom was also in competition with Westover Air Reserve Base and Tinker Air Force Base for basing of the KC-46A.

Role and operations
The host wing for Grissom Air Reserve Base is the 434th Air Refueling Wing (434 ARW) of the Air Force Reserve Command (AFRC). As a result of previous post-Vietnam War base realignments and post-Cold War BRAC realignments, AFRC currently controls four former active duty Air Force Bases in the United States that have been re-designated as Air Reserve Bases (e.g., Grissom ARB, IN; Homestead ARB, FL; March ARB, CA; Westover ARB, MA).

Grissom ARB also hosts Army Reserve and Marine Corps Reserve units.

The base has a combined workforce consisting of both military personnel and civilians and ranked as the largest employer in Miami County and the third-largest employer in north-central Indiana in 2012. Grissom claims an economic impact of over $130 million per year, and is involved in community activities, like the Marine Corps Reserve's annual "Toys for Tots". The National Arbor Day Foundation designated the base as a "Tree City". In 2017, Grissom Air Reserve Base became home to the Green Knights Military Motorcycle Club, Chapter 109, an official chapter of the Green Knights International Military Motorcycle Club. The club promotes motorcycle safety for both military and civilian personnel and is open to all active, reserve, and guard military members, DoD Civilians, DoD Contractors, and Retirees.

Environmental problems
In 2015, groundwater at about 20 feet below the surface was found to be contaminated with perfluorinated compounds (PFCs) at two former fire-training areas. PFCs are found in fire-suppressing foam used to extinguish petroleum-driven aircraft fires. The drinking-water wells near the base go much deeper, at 150 to 180 feet below the surface. At around 14 other sites on or near the base pollutants, like vinyl chloride, in soil or water are also being investigated. In September 2015, four water wells closest to the former firefighter training areas tested negative for PFC's as did the in-flow and out-flow points at the nearby city of Peru's municipal water treatment plant with levels below the EPA health advisory limits.

The Air Force has been testing 82 former and active installations nationwide for PFC's. In 2015, PFCs were found in groundwater at the former Naval Air Station Brunswick and well water at Pease Air National Guard Base.
