Turkey's ROKETSAN missiles to use domestic turbojet engine

Turkish defense contractor Roketsan has said its future missile systems will use fully domestic turbojet engines created for Turkey's stand-off-munition cruise missile, SOM, as of next year.

The turbojet engines will add to Turkey's growing list of domestic defense products. SOM cruise missiles were developed by the Scientific and Technological Research Council of Turkey's (TÜBİTAK) Defense Industry Research and Development Institute (SAGE) and produced by Roketsan.

Recently the Undersecretariat of Defense Industry and Kale Aviation Industry Inc. signed a contract that included the design, production, testing, technology demonstration, training, maintenance and technical data package of the turbojet engine and related subsystems to be used in the mass production of SOM missiles, as required by the Turkish Air Force Command.

Kale Aviation is getting ready to finalize its efforts for turbojet engines supplied from abroad. Turbojet engines will be used in SOM missiles as of the middle of next year. So, a critical part of the missiles will have been procured more economically and possible export restrictions will have been prevented.

The finished system could also be used in SOM-like systems, unmanned aerial vehicles and small-class aircraft with minor modifications.

The project has allowed making significant gains in the reduction of external dependency on engine technologies.

The first gain is the development of sub-systems such as alternators, fuel pumps, fuel control systems, electronic control units and pyrotechnic igniters, which could also be used in other engines. In addition, the project also saw the development of compressors, core engines, combustion chambers and turbines. The second major gain is national and original development of all development testing mechanisms, considered a must to develop a new jet engine. The SOM missile family, designed for use against ground and sea targets, comes in different variants including the SOM-A, SOM-B1, SOM-B2, and SOM-J.

The missiles have an operational range of more than 250 kilometers and offer low visibility, high precision, resistance/endurance against mixing measures, network-based movement suitability, engagement with opportunity targets and selection between pre-planned tasks during flight, target definition during flight, selectable stroke parameters and universal weapon interface compatibility.

Good job. I see some serious progress here.

Turkey Takes Defense Indigenization Another Step Forward
Dec 15, 2017

A new engine will be developed for Turkey’s cruise missiles. The Turkish Havacılık (Kale Aero) company has won a contract from the nation’s under-secretariat of defense industries (SSM) to design, develop and produce a miniature turbojet engine for Roketsan’s new cruise missiles, including Standoff Missile (SOM).

According to quwa.org, the SOM is a result of Turkey’s longstanding indigenization drive aimed at reducing the country’s reliance on overseas suppliers for weapons. This is a particularly sensitive issue with stand-off weapons (SOW), which can be costly to procure from overseas and potentially subject to export restrictions.

Currently, the Roketsan SOM and Atmaca anti-ship missile (AShM) rely on the Safran Microturbo TRI 40.


According to defenseworld.net, Turkey identified the need to develop, test and manufacture sub-systems such as alternator, fuel control system, electronic control unit, fuel pump, pyrotechnic igniter and combustion chamber. It also needed to develop testing equipment.

The range of the SOM reaches over 250 km. It has a total weight of 589 kg, with the warhead taking up 227 kg. In turn, the SOM’s warhead options are High Explosive and Blast Fragmentation, with guidance options including satellite-aided inertial navigation and terrain reference.

Roketsan is also working with Lockheed Martin to develop the SOM-J, a smaller variant for use from the F-35 Lightning II’s internal weapons bay.

The engine production is scheduled to begin next year.

The Atmaca, a sea-skimming AShM, will be joining the SOM soon. In October, the Turkish Navy announced that the Atmaca had undergone successful firing tests. Designed as an analogous solution to the MBDA Exocet and Boeing Harpoon, the Atmaca weighs 800 kg (with a 200 kg warhead) and relies on a mid-course INS/GPS guidance suite.

Ibrahim Sünnetci Chief Editor from S&H said that Turkey will go a long time with Safran engines, cause a long lasting production contract was signed and based on it Safran developed a complete new TR-40 which meets almost the power of the TR-50, exceeds TR-50 in some parameters and has a complete new lubrification system. This engine will be used for GEZGIN cruise missile. He added, that SOM-ER project maybe cancelled. SOM family except SOM-J and Atmaca Blok-1 will use TR-40, SOM-J will be equipped with the new version of TR-40. They will be delivered in 2018. He added that he knows the details of the contract and specs but isn't allowed to publish them.
