We’ve all heard of the Hellfire missile, the primary weapon of the AH-64D Apache helicopter. Goodness knows, we’ve showed enough videos here of Hellfires landing on the heads of jihadis in Iraq and Afghanistan.
Britain liked the Hellfire. They have used them for years on their own fleet of Apaches. In fact, they liked it so much, they wanted to adapt it to be used from their fast jet fleet. But Britain also wanted to get away from the Hellfire’s semi-active laser seeker, and instead use a “fire and forget” millimeter-wavelength radar seeker.
Eventually, the redesigned missile, now known as Brimstone (which, yeah, the next logical name after hellfire), entered service in 2005. But it also became apparent that the positive control of a semi-active laser seeker was a handy feature. Accordingly, the Brits cleverly designed a “dual mode” seeker, allowing the shooter to fire in either millimeter-wave mode, or laser mode. In radar mode, it can be ripple fired to engage multiple targets. In fact, our Navy is looking closely at Brimstone to counter swarming boat attacks.
The British used Brimstone with good results throughout the campaign in Libya.
