Military Technical Institute

Military Technical Institute (Војнотехнички институт; abbr. VTI) is a Serbian weapons and aircraft design institute, headquartered in Belgrade, and governed by the Serbian Ministry of Defence. It is a top-level military scientific research institution in Serbia, dealing with research and development (R&D) of new weaponry and military equipment as well as with upgrade of the inventory for both branches of the Serbian Armed Forces: Army (including River Flotilla) and Air Force and Defence.

Institute history
After the World War II, Federal People's Republic of Yugoslavia had a need to independently develop military technology and reduce dependence from foreign supply with given political situation of that time and future political course. By a decision of the Secretary of Defense and a proclamation by the Yugoslav president Josip Broz Tito, VTI was founded in 1948 as the Military Technical Institute of the Land Forces (Vojnotehnički institut Kopnene vojske; abbr. VTIkov) in Belgrade.

In 1973, the VTI was integrated with several smaller military research and development institutes.

In 1992 it assimilated the dissolved Aeronautical Technical Institute in Žarkovo, and minor parts (located in Serbia) of the Nautical Institute (Brodarski institut) from Zagreb, supposedly as an effort to reduce developing cost and maintenance. Since 1992 the institute has changed name several times, reflecting the political changes in the country, starting with Technical Institute of the Yugoslav Armed Forces.

Current name is Military Technical Institute. Neither the translation of the name to other languages nor the corresponding acronym have ever been unambiguously defined; both VTI and MTI have been used in English-language documents, against the widely accepted practice not to translate such acronyms.

Today
The institute has 22 laboratories, and it is situated on 212 acres (86 hectares), with 177,000 square meters laboratories and office space, mostly in Belgrade neighborhood of Žarkovo, on the premises of the former Aeronautical Technical Institute. The institute obtained the certificates of compliance to the SRPS ISO 9001 and SRPS ISO/IEC 17025 standards.

Projects
The institute cooperates with Serbian Armed Forces (including its Technical Testing Center) and Yugoimport SDPR in designing and testing new weapons systems.

Military Technical Institute (with assimilated predecessor institutes) developed more than 1,300 weapons. However, not all of them entered use in the Yugoslav (later Serbian) Army. The list includes weapons and systems of other companies in which VTI was partly involved in some stage of developing and those systems are given with references. Institute was in charge for domestically produced weapons systems under licence and modification and modernization of such weapons with introducing new technologies and making new materials and tools for production. There are several new weapons developed from licences products that surpass originals in performance. Examples of licences used for domestic new weapons is a licence for tank T-72.

The institute possesses technical documentation for over 1300 items of weaponry and defense equipment developed through institute history that are introduced in service in the armed forces. This documentation being intellectual property of MoD, it has an outstanding value and use for future projects.
