Advanced Anti-Ship Missile Guide

The Helicopter Strike Missile (HSM) is a long range, fire-and-forget anti-ship cruise missile that can be launched from helicopters or maritime patrol aircraft. It uses inertial guidance and a dual-band imaging infrared seeker to autonomously locate, track, and home in on targets without requiring further guidance from the launch platform. The HSM has a range of over 130km and can engage targets from outside the range of enemy air defense systems. It was developed based on the successful Naval Strike Missile and provides an extended-range option for deploying from helicopters.

Helicopter Strike Missile (HSM)

- Attack without Warning


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 360 firing arc allows the helicopter to prosecute/engage targets on any bearing relative to the helicopters 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. Main Features State-of-the-art, all digital, fifth generation fire-and-forget anti-ship strike missile Numerous selectable flight profiles and horizontal trajectories Stand-off range from outside opponents area air defense systems Accurate passive midcourse guidance Passive state-of-the-art infrared seeker Autonomous target validation, tracking and homing Unaffected by jamming and IR decoys Random high-g maneuvers in terminal phase Impact point close to waterline for maximum destructing effect in target

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 Norwegian 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.
