On the 1st of April, 1942 by the Decree of State Defense Committee Chairman J. V. Stalin there was established the Special Design Bureau of People's Commissariat for shipbuilding industry of USSR (SPD PCSI).

At the end of 1942 the SPD PCSI was transformed into the Maritime Research Institute No. 1 (MRI No.1). Initially when establishing the SPD PCSI it was entrusted to work in the sphere of mine and torpedo weapon development.

In the august, 1945 on the basis of Order of People's Commissariat for shipbuilding industry there was established the Leningrad subsidiary of SDB. The direction of works and the structure of the Leningrad SDB subsidiary were analogous to the bureau in Moscow.
In the years of the Great Patriotic War and post-war years the MRI No.1 developed several dozens of the most sophisticated at the time fire control systems for torpedo and artillery weapon; almost all types of ships were equipped with these systems. In the future the research engineering and experimental works carried out by MRI No.1 gave the opportunity to create fire control systems that ensured safe launching of cruise missiles from different types of ships and under any weather conditions on sea.

In 1960 the SPD PCSI was turned into the Central Maritime Research Institute.

In 1972 the Central Research Institute Agat was established (CRI Agat).
The main guidelines of CMRI and then of CRI Agat were the development of digital means for computer engineering meant for different sea objects and the creation on its basis the automated control system for the submarines and surface ships combat actions.

In 1978 on the ground of CRI Agat there was formed a mighty Scientific Production Association Agat (SPA Agat) that included CRI Agat, Pilot plant Agat, Subsidiary of CRI Agat in Erevan and Erevan instrument engineering plant Bazalt. SPA Agat was conferred with the Order of Lenin for the outstanding success in strengthening the defence capability of the country and efficient work on the development of radioelectronic weapon for the Navy.

In 2004 in accordance with the Russian Federation Presidential Edict No. 134 of 3 February, 2004, «About Concern Morinformsystem-Agat Joint Stock Company, on the basis of SPA Agat FSUE there was formed the Concern Morinformsystem-Agat JSC that included the Scientific Production Association Mars, the Central Research Institute Kurs, the Production Association Binom and the Research and Production Enterprise Kaluga Instrument-Making Plant Typhoon.

In 2007 in compliance with the Russian Federation Presidential Edict No. 397 of 21 March, 2007, «About the development of Concern Morinformsystem-Agat Joint Stock Company, in Concern Morinformsystem-Agat  JSC there were included Production Association  Kometa, Research and Production Firm Meridian, Plant Izumrud, Design Bureau Ametist, Plant Topaz and Plant Salyut.

In 2009 as provided by Russian Federation Presidential Edict No. 971 of 24 August, 2009 «About the further development of Concern Morinformsystem-Agat Joint Stock Company, in Concern Morinformsystem-Agat JSC there were included Plant Elektropribor, Kamchatka Hydrophysical Institute, Scientific Research Institute Atoll.
