UK Apache has the following weapons: Hellfire K and L, CRV7 rockets with various warheads and 30mm M230 gun with various types of ammunition. There are no plans to carry Brimstone.

There was an article in AFM a few months that had British Army WAH-64s firing both HEAT and blast/frag/(incendiary?) laser versions of the SALH Hellfire II (presumably AGM-114M) in an exercise in the States.

The UK Merlin does not carry rockets, nor is it likely to; neither does the current UK Lynx, although that could change when the Future Lynx comes along.

Hi. Gazelles carried two small pods (6 per pod?) of 68mm rockets in the Falklands. I’ve seen early commando Wessexes (mid-late 1960s) with podded rockets (I think they were 2″ ones the RN used from fixed wing aircraft ), SS-11 or 12 ATGM and what looked like fixed forward firing .303 Brownings! I think the British Army Apaches use CRV-7 – though I’ve only seen the 19 round pods.
