RU vai equipar os F-35 com mísseis Spear 3

By Duncan Mil

January 12, 2021 - A Marinha Real britânica vai equipar os caças furtivos F-35B Lightningque operam a partir do HMS Queen Elizabeth e HMS Prince of Wales comos minimísseis de cruzeiro de próxima geração Spear 3.

In a recent €610 million (£550 million) deal with European weapons-maker MBDA, Spear 3 will become the F-35B’s principal strike weapon. The missile can knock out warships, tanks and armoured vehicles, missile launchers, bunkers, radar posts and air defence batteries.

Powered by a Pratt & Whitney TJ-150 turbojet, the missile flies at high subsonic speeds with a range of more than 140 kilometres.

The Spear 3 incorporates a multi-mode sensor seeker with millimetre wave (MMW) and Semi-Active Laser (SAL) or targeting flexibility. The seeker captures images at near optical wavelengths (94Ghz) producing high-resolution images for the system’s target recognition algorithms to evaluate.

The SAL seeker allows a special forces Forward Air Controller to “paint” a target for the missile using a laser. The seeker locks on to the laser’s reflected energy and flies itself to the target. The MMW seeker enables “fire and forget” missions.

A multi-effects warhead can be reprogrammed during flight and can produce a shaped-charge effect against armour, fragmentation effects against “soft” vehicles, or penetrate hardened structures and bunkers.

Spear 3 will become the principal strike weapon of the F-35Bs based on the HMS Queen Elizabeth Carrier Strike Group when it enters service in the mid-2020s.
