In November 1981 Bell Helicopters presented their concept of an anti-tank helicopter, the Panzerabwehrhubschrauber – 2 (PAH-2), to the German Army.
This concept was based on the Bell Model 249 Cobra. It had a 4-blade main rotor (a smaller version of the Bell Model 412 main rotor). It was powered by a single General Electric T700 engine with max. 1650shp.
The Martin Marietta Target Acquisition and Designation Sights, Pilot Night Vision System (TADS/PNVS) is the combined sensor and targeting unit which was fitted on the nose. There were 4 stations on the stubbed wings to hold weapons like HOT anti-tank missiles, unguided missiles, Stinger A2A missiles, gun pods etc. Like other PAH-2 concepts at that time, this concept also did not have a central chain gun. Later on the AGM-114 Hellfire might have been integrated.
The Bell Model 249 PAH-2 would have been built under licence by Dornier at their final production site near Oberpfaffenhofen, Germany. At that site the Bell UH-1D were already built under licence for service with the German Army and German Air Force. The US Army in Europe also had their older AH-1 Cobra models upgraded at that site (AH-1Q’s to AH-1S’s ?).
In the early 80’s a Bell Model 249, actually a Bell AH-1S with a 4-blade main rotor, was tested at the Wehrtechnische Dienststelle 61 on the Manching Air Base.

In the same time period Agusta helicopters also presented the Agusta A.129 Option D (D= Deutschland/Germany?) to the German Army. It was basically a normal A.129 fitted the TADS/PNVS system.
The German Army were very interested in the TADS/PNVS system, because nearly all PAH-2 concepts like the MBB PAH-2, the Bell Model 249 PAH-2 and Agusta A.129 Option D had that system in the front fuselage.
Other helicopters concepts like the British Lynx or the French Dauphin/Panther with the side-by-side seating were cut out in this program. According to the German Army at that time, the side-by-side seating gave a poor all-around visibility.
Years later, Bell Helicopter proposed again a PAH-2 concept to the German Army. This time the concept was based on the helicopters AH-1W and AH-1(4B)W Viper as flown now by the USMC.
