OTO HITROLE® 12.7mm naval turret is a modern system fully controlled from a remote station via an advanced control console. This allows the gunner to operate from a protected position within the ship’s structure - any operation, including loading and recocking, can be undertaken with maximum safety for the operator.

Low weight and high level of flexibility make this turret particularly suitable for installation as main armament of a small patrol vessel engaged in border control or maritime traffic interdiction, or as a secondary armament on larger ships for self defence in the anti-terrorism role.

The turret is electrically operated and very accurate due to powerful digital servos. Sighting and tracking actions are performed by means of a high performance day TV camera.

Ballistic Routine is available to provide aid whilst engaging moving targets. Additional options include IR sensor for night operation as well as a Laser Range Finder and Auto Tracker. The sensor suite is protected within a watertight shelter.

The OTO HITROLE® 12.7mm turret is a stand-alone system with stabilisation provided through a integrated gyros. The turret requires no external signal from other ship systems.

Upon request, the OTO HITROLE® 12.7mm turret can be linked to other Electro Optical (EO) sensors on board the ship. A functional interface to the ship’s Combat Management System (CMS) can also be provided.

For special operations the 12.7mm (0.50” calibre) machine gun can be replaced with a 40mm Automatic Grenade Launcher (40mm AGL), which is also capable of firing ‘non lethal ammunition’. The weapon reconfiguration can be achieved in a few minutes with no special tools required.

Belted rounds are available for both the 12.7mm machine gun and the 40mm AGL in standard ammunition boxes, (130 rounds for the 12.7mm machine gun and 32 rounds for the 40mm AGL).

An optional ammunition loading system can be installed in a dedicated support in order to increase the available 12.7mm capacity up to 400 rounds.
