Im a bit surprised. Isnt the apache a bit outdated`? The first apaches were introduced in 1975. Ok its a good helicopter I have no doubt about that.
I can understand what you are saying, but like anything, the British WAH-64 has been totally updated. The greatest upgrade in the Longbow radar system.
The GKN Westland WAH-64 Apache helicopter was chosen as the future attack helicopter for the British Army in June 1995. Led by GKN Westland Helicopters Ltd., the Westland Apache Team includes more than 170 companies in the UK, plus Lockheed Martin, Boeing Helicopter and Northrop Grumman in the US.
A joint venture between Lockheed Martin (Missiles and Fire Control) and Northrop Grumman, the Longbow Limited Liability Company (LLLC) is currently delivering the Longbow Fire Control Radar system for the British Army’s WAH-64 Westland Apache attack helicopters.
The Longbow integrated fire control radar and missile system is at the heart of the Apache system, enabling the crew to track up to 256 ground targets simultaneously for engagement by a new generation of radar-guided ‘fire-and-forget" Hellfire anti-tank missiles.
The radar and missile combination enables the Apache to detect, classify and prioritise ground targets, day or night, in poor weather and in obscured conditions; then engage those targets with pinpoint accuracy from ranges that safeguard the lives of British pilots. (Source - Lockheed Martin)
Even if the airframe is 34 years old, if it work well, use it. Look at the EE Canberra, 55 years service and it could had gone on longer.
