The GWS.41 Loon is an anti-submarine missile that can be launched either from surface ships or submarines. It carries 200-350kg lightweight (i.e. 324mm) torpedo to the last noted position of the target before releasing its payload.

The weight of the launch vehicle, with booster but without the torpedo, is about 500kg (497.94kg; 376.71kg without booster). With an MU 90 torpedo, the Loon can attain a range of up to 60km, with an initial speed (ballistic phase) of up to Mach 2.25. The launch vehicle can be continuously updated by the firing vessel while in flight. Once the booster engine has been detached, the Loon cruises to the target using a high efficiency turbojet engine at trans-sonic (high subsonic) speed. Above the target, the launch vehicle releases the payload, which then parachutes into the water and proceeds to seek its foe.

The Loon can be launched by a ship equipped with a Mk.41 VLS, or a ship or submarine able to fire a Tomahawk missile.
