Abraham Gubler said:From memory and the Bell bid for the Australian AIR 87 project the AH-1Z (or AH-1W(4BW) as it was once known) was to be (re)built with the 30x113mm M230 chaingun. But the 20x102mm M197 Gatling gun was retained as a cost saving measure. 30mm was more capable but 20mm was already paid for.
F-14D said:Australia was offered the Cobra twice. First, 40 AH-1Ws in the early '90s.
F-14D said:Then, the -Z was offered for the Air 87 competition. it was eliminated in 1999 because it was deemed "too developmental", and the three contractors selected to proceed were Agusta (Mangusta), Boeing (Apache) and Eurocopter (Tiger). the latter won, but ironically has had so many delays that it didn't achieve full operational capability any sooner than the "developmental" Zulu Cobra.
F-14D said:I never knew that the Air 87 Zulu was intended to have the M230. Interesting detail I'll have to keep in mind...

Actually this was the second time. The first time Australia actually ordered 11 AH-1Gs from Bell for delivery in ’72 but a change in government and rapid withdrawal from VietNam saw a last minute cancellation. The Cobras were to replace armed UH-1D “Bushrangers” and equip two gunship flights in two tactical helicopter squadrons (No. 9 and the planned to form No. 8 Squadron). The USMC AH-1Ws offered in the early 90s were the rebuilt AH-1Ts and alter sold to Taiwan (a somewhat common habit for ex US gear: offer to Australia, get rejected and sell to Taiwan). It was an obvious great loss to the Australian Army that these Cobras were not acquired at this date.

Tony Williams said:Saboted ammo can't generally be used by fixed-wing planes because of the danger of the sabots being sucked into the engines, but presumably the location of the gun in the AH1, plus the powerful rotor downdraft, mean that the sabots drop down well away from the intakes.
