Turkish Roketsan, Lockheed Martin sign Stand-off Missile deal For F-35s

Roketsan and Lockheed Martin signed a teaming agreement today for collaboration on the SOM-J, a new generation air-to-surface Standoff Cruise Missile for the F-35 Lightning II.

The SOM system is an autonomous, long-range, low-observable, all-weather, precision air-to-surface cruise missile. The SOM-J variant is tailored for internal carriage on the F-35 aircraft. The companies will jointly develop, produce, market
and support SOM-J for internal carriage on the F-35 aircraft or external carriage on
other aircraft.

Lockheed Martin Missiles and Fire Control Executive Vice President Rick Edwards and Roketsan Chairman of the Board Eyüp Kaptan signed the agreement.

“Lockheed Martin has a long history of partnership with the Republic of Turkey, and we look forward to working closely with Roketsan on this very important project,” Edwards said. “SOM-J will provide the F-35 and other aircraft an exceptional capability to meet the most challenging mission requirements. We look forward to combining the skills and know-how of our two great companies to produce a world-class system to meet customers’ expanding needs for long-range, survivable cruise missile technology.”

“At Roketsan, we believe this teaming will increase the attention on SOM-J and present a superior solution to fulfill the requirements of anti-surface warfare capabilities on the F-35 aircraft,” Kaptan said. "Within the (F-35) Joint Strike Fighter project there is no other cruise missile with the capabilities of the SOM-J, I think the SOM-J will be an important option for other countries in the project including the United States."

Roketsan Inc. was founded in 1988 for the purpose of “possessing a leading institution in the country for designing, developing and manufacturing rockets and missiles.” Roketsan is rapidly going forward to become a global company in defense industries sector with personnel of more than 1,800, 51 percent of which comprise engineers, an invested capital of TL 4 billion and its accumulation of technologic knowledge. Roketsan has become a corporation, the operations of which now extend beyond the borders of the country, which participates in NATO programs in its field of technology and is capable of supplying its products to friendly countries besides the Turkish Armed Forces.

Developed since 2006 by defense research and development institute TÜBİTAK-Sage, the SOM is Turkey’s first domestic weapon to attack stationary and moving targets at a standoff distance of more than 180 kilometers. The SOM-J is known as a reduced size version of the SOM.


The SOM stand-off cruise missile is a family of launch and leave precision strike weapons against both land or sea targets. It uses GPS as its primary mode of guidance complemented by an advanced Inertial Navigation System and a radar-based Terrain Referenced Navigation system, allowing the missile to skim the terrain during its flight in order to evade local defence systems. It features advanced geometry and aerodynamics over similar missile systems, as well as lightweight composite components that minimize the radar cross-section of the missile. A terminal stage infrared imager detects the individual target by matching its signature with a pre-loaded database of similar targets allowing for precision strike. It can also be used to provide image-based midcourse navigation by taking snapshots of waypoints and comparing them against predicted position to update the navigation system. By this way, if GPS capability is denied or degraded, the missile can follow its waypoints using infrared based terrain updates. The missile includes a two-way datalink that makes possible to change the task in flight.

Basic design of the missile incorporates dedicated fuselage that fits in the internal bays of the Joint Strike Fighter.

It is intended to achieve high accuracy in striking military targets like command and control facilities, SAM sites, parked aircraft and surface ships.
