French Caiman

According to Defense-Aerospace.com, the Caiman helicopter has now obtained its combat qualification in the Anti-Submarine Warfare (ASW) role. Friday, March 13, 2015 was an important date in the history of the NH90 Caiman Marine helicopter, which after qualifying to operate the MU90 lightweight torpedo had been certified as having attained an initial combat capability by the French Navy staff.

This is a significant milestone for the FREMM frigate/Caiman operational duo, which is qualified for engaging the most up-to-date submarine threats at longer stand-off ranges.

The French Navy’s Caiman saga began with the delivery of the first helicopter on May 2010. It was followed in December 2011 by the type’s first «rescue alert» mission on the Atlantic coast and on a nation-wide stand-by for «maritime anti-terrorism» missions. In February 2013, the Caiman qualified for the «Ship-based Anti-Submarine Warfare» mission, in support of the Navy’s strategic missile submarines and of the aircraft carrier task force.

A naval Caiman is currently deployed on board the air-defense frigate Chevalier Paul (D621), which is currently deployed to the Middle East on operation Arromanches.

The mission system in the NH90 NFH is an all-in-one system that allows autonomous and joint ASW, ASuW and SAR operations without role change
