Future Assault Shell Technology helmet

The Ops-Core Future Assault Shell Technology (FAST) Helmet, also known as the FAST helmet, is an American combat helmet used by special operations forces and law enforcement organizations in various countries, as well as the current standard protective headgear of the Norwegian Armed Forces.

The FAST helmet series features a distinctive shell shape, with ear cut geometry which extends coverage over the rear occipital bone without load carrier interference, and optimizes weight distribution for increased stability, integration, balance, and comfort. The helmet features various suspension and retention systems, and ARC rails which, similar to picatinny rails, enable users to mount items like helmet lights and cameras.

History
It was developed by the U.S. Army Research Laboratory in collaboration with the U.S. Army Natick Soldier Research, Development and Engineering Center and the Program Executive Office (PEO) Soldier as part of the Army Manufacturing Technology (ManTech) Program, which also led to the development of the Enhanced Combat Helmet (ECH).

The name FAST helmet was coined by a manufacturing company called Ops-Core in 2005. In 2008, Ops-Core showed off their prototype helmet with their Head-Loc™ Helmet Retention System (a.k.a. Head-Loc Retention System) at the 2008 SHOT Show convention. The helmet was publicly revealed in 2009 at the annual SHOT Show. It was issued to U.S. special forces operators deployed in Afghanistan.

In 2019, U.S. Special Operations Command awarded Gentex a contract worth $95 million to supply Ops-Core FAST SF Super High Cut Helmets that were released in 2018.

Development
Compared to standard combat helmets, the FAST helmet offers up to 25% weight reduction and is notable for its early use of ultra-high-molecular-weight polyethylene fibers (UHMWPE) in its design. It was also designed to allow outside features such as wearing communications headsets which can be attached with rail adapters.

Design
The FAST helmet ranges in weight from about 667–1592 g (1.47–3.51 lbs). The type of UHMWPE material for the ballistic FAST models provides increased protection against NIJ Level IIIA handgun rounds. It can be fitted with a mounting bracket, patented first in 2014, for accessories like night vision goggles and communications headsets, similar to PASGT and MICH. Users can wear it with different communications headsets with ease and comfort. The Velcro featured on to the helmet also allows for the wearer to attach national flag or the emblem of unit which they belong to, in addition to other IFF (Identification friend or foe) patches such as call sign and blood type

It has different color options, such as foliage green, black, olive green, ranger green, tan 499, urban grey, MultiCam and desert MARPAT. As well as having mesh and cloth helmet covers in varying camouflage patterns.

The FAST RF1 High Cut Helmet System released in 2021 is a rifle rated ballistic helmet at an average of 3.5 lbs (1592 grams) able to protect against rifle rounds like the 7.62×39mm and 7.62x51mm due to the 0.400" (10.16mm) shell thickness. The different color options are tan 499, ranger green, MultiCam, black, and urban gray.

The FAST XR Helmet System released in 2022 represents an intermediate in protection between the SF line of helmets and the RF1 Helmet System, protecting against 7.62×39mm rifle rounds at a distance of 10 feet, but not against larger rounds such as 7.62×51mm. This is due to having a shell thickness of 0.280" (7.112mm). It is far lighter than the RF1, averaging at only about half a pound heavier than the SF helmet, depending on the type of chinstrap. It is available in Tan 499, Ranger Green, MultiCam, Black, and Urban Gray.

In addition to military and law enforcement, the non-ballistic version of the helmet also has gained considerable popularity among civilian occupations, such as outdoor sportsmen, journalists, disaster relief personnel and other field workers due to its modular design.

Users
The FAST family of helmets are ubiquitous across military, police, and other uniformed services around the world.
