Aselsan develops advanced naval STAMP RWS

04 May 2017

Turkey's Aselsan has released details of a new remotely operated weapon station (RWS) designed for mounting on naval vessels.

The Stabilised Machine gun Platform-2 (STAMP-2) features several improvements to the original STAMP design, and was developed in conjunction with TUBITAK, the Scientific and Technological Research Council of Turkey.

STAMP-2's design is similar in configuration to the original system, armed with a 7.62 mm or 12.7 mm machine gun or 40 mm automatic grenade launcher (AGL) in a cradle-type mount with a sight to the right-hand side. Unlike the original STAMP, however, the STAMP-2 can use the Soviet-origin 12.7 mm NSV machine gun. The weapon can also be elevated between -20 and 60°, compared to the -15 and 55° of the original STAMP. The gun and independent sight can both be traversed and elevated at a rate of 60° per second, completing a full rotation in six seconds.

The new RWS' electro-optical sight can be operated independently of the weapon, and is a panoramic unit positioned on a rotating ring mount. The previous design mounted the sight system on the side of the weapon cradle, preventing independent movement from the weapon. This feature of the STAMP-2 enables the system to be used for surveillance. The sight's laser rangefinder and day and thermal sensors are reconfigured compared to the STAMP, arranged in a more compact rectangular box that can also be elevated independently of the weapon mount.

This redesigned sensor mast is known as the High Accuracy Stabilised Gimbal (HASG) and extends the engagement range of the STAMP-2 compared to STAMP, according to Aselsan. The HASG was developed originally for the STAMP-PLUS, on which it is capable of fall-of-shot observation at a range of at least 1,500 m using 12.7 mm ammunition with tracer.

The STAMP-2, unlike the original STAMP, can be connected to other RWSs within a network.
