OK my dear Rolf,and nice find.

Speaking of which they were offered the Bell 409 4 bladed Cobra as a PAH-2 in the 80s and the then McDonnell Douglas AH-64A

U.K.-German anti-tank helicopter

At the start of the Paris Air Show
Westland announced that they are
collaborating with VFW-Fokker of
Bremen on the design of a new anti-tank
helicopter, the P.277, intended to meet
the West German Army's PAH-2 (Panzer
Abwehr Hubschrauber) requirement.
Employing the Westland Lynx's rotor.
transmission and twin Rolls-Royce Gem
4 engines, the P.277 would have a maximum
mission weight of 9,500 lb., cruise
at 150 kt., climb at 2,650 ft./min., and
have a range of 315 naut. miles.
All-weather/night capability, nap-of-the-
earth agility and high speed are
regarded as essential features and the
two-crew P.277 could be armed with
eight HOT or TOW missiles and a 20/30mm.
cannon in a chin turret, or twin
rocket pods, MATRA 550 missiles, and
a 7.62-mm. gun. Entry into service would
be around 1985-6.

Thanks

Westland-VFW Fokker P277:

P277 followed from 1976 and was the identity assigned to the armed attack helicopter project collaboration between Westland and VFW-Fokker that was publicly announced in 1977 and which took as its baseline the Yeovil Future Project team’s “Wildcat” configuration. The aircraft was aimed at the emerging German army requirement for a second generation “Panzer Abwehr Hubschrauber” (PAH-2) to follow on the interim MBB BO105 based PAH-1. Extensive wind tunnel tests were completed for the first time on this configuration at the VFW-Fokker facility in Bremen.(12)
A full-size mock-up was built by VFW-Fokker along with a human factors cockpit test facility. The only major change to the “Wildcat” configuration presented in 1975 was a further engine upgrade to the Gem 4 standard and an increase in maximum take-off weight to 4,760 kg (10,500 lb). During the detailed definition of this aircraft its canopy would once more be modified to a “stepped” arrangement, offering the pilot a much-improved view forwards in poor weather and also minimising the mass of armour separating the two cockpit stations (Figure 10).
The formal German PAH 2 requirement, thought imminent in 1977, was not actually formally issued until 1983, by which time the acquisition of VFW-Fokker by Messerschmitt-Bölkow-Blohm (MBB) in 1981, combined with the political desire for a Franco/German collaboration ruled out any possibility of the P277 being taken any further.

Westland WG.37 Warrior:

All substantive work on a dedicated two seat armed attack variant of Lynx now ceased but the Future Projects group maintained a close relationship with the Operator through the auspices of the Military Advisory Liaison Team (MALT) based at Yeovil and staffed by Colonels Moss and Waddy, both retired.
Through this relationship the Company remained convinced that the Operators’ desires for an effective anti-armour weapon system would eventually result in a resurgence in UK interest in this class of vehicle. The P277 was a solution that could be implemented quickly and at the lowest possible cost but it did not offer a transformation of capability that was seen in some quarters as necessary to combat the Warsaw Pact (WP) threat to NATO. This desire was later to be carried through in large part to the flight performance requirements sought in the Light Attack Helicopter Staff Target GST3971, which is discussed further in Section 8.2.
A 1979 presentation to Major General Ian Baker of ACGS(OR) was intended to focus on a range of concepts that might realise significant commonality across a wide range of airframe types appropriate to all battlefield uses of rotorcraft.(13) The context was the extant “Pathfinder” R & D program that was envisioned as the route to fielding advanced technology for the rotors, transmission, and structures.
Alongside these ideas the Company presented its vision for a revolutionary combat rotorcraft by way of an example of the technological consequences of fielding significantly increased speed, agility and survivability. This was project WG.37 Advanced Combat Helicopter, aka “Warrior” in Project Office parlance, which had resulted from studies of high-speed rotorcraft configurations and technology, previously completed under the sponsorship of the RAE materials and Structures Department. “Warrior” was configured with a co-axial lift offset rotor having

In some ways it mirrored the technology anticipated by the US Army 2004 Future Vertical Lift (FVL) program and the subsequent Future Armed Reconnaissance Aircraft (FARA) program initiated by the US Army during 2019.
