RTN-10X „Orion“

The RTN-10X „Orion“ alias MM/SPG-70 (MM stands for Marina Militare, a nomenclature for the Italian Navy, similar to the US-Army/Navy's nomenclature AN/…) is an operating in I-Band tracking and fire-control radar. In UK Royal Navy got this radar the designation Type 912.

The radar has two operating channels: pulse mode for target search and continuous wave mode for target illumination. The antenna is a slatted paraboloid reflector. It is based on a conical scan narrow beam antenna, with a tri-port feed and uses a magnetron with fast tuning capabilities.

RTN-10X „Orion“ used in conjunction with different fire-control systems to control gun and missile firings. It is suitable for installation on ships of any size from fast-attack craft upwards.

RTN-12X „Sirio“

RTN-12X „Sirio“ alias MM/SPG-73 is a stripped down variant of RTN-10X. It is a continuous wave radar specifically designed to act as a target illuminator for semi-active homing missiles. It uses the same antenna without the camera and without the breakthrough for the camera.
