The Helicopter Strike Missile (HSM) is a true state-of-the-art long range anti-ship cruise missile, which combines precision inertial guidance with a high-resolution dual band imaging infrared (IR) seeker with unique search geometry. The missile does not require any in-flight guidance from the launching platform and the seeker will autonomously locate, verify and home on target. A complete 360º firing arc allows the helicopter to prosecute/engage targets on any bearing relative to the helicopter’s heading without having to change its course. This missile has been in development since 2001 and is ready for helicopter and maritime patrol aircraft integration.

Background

Infrared guided fire and forget missiles are key assets in the inventory of the Norwegian Defence Forces. The Royal Norwegian Navy, the Defense Research Establishment (FFI) and KONGSBERG have each made their contributions in the development of these IR missiles. The Penguin missile is the market leader for the naval helicopter application. The modernization of the Royal Norwe-gian Navy resulted in a requirement for a longer range missile deployable in a global setting and designed to counter the threats of 2017 and beyond. This lead to the development of the Naval Strike Missile (NSM) which from the outset was designed for ships, helicopters, and truck launches. The Helicopter Strike Missile (HSM) is a spin-off from the Naval Strike Missile (NSM) development with the same seeker, electronics, warhead, motor and booster.
