The Mossie Killer was developed as production ready fighter since 1938 (FW 187)
I don't understand how the Germans could build a Mossie killer before the Mossie had even been built! Nevertheless, valid points, DonL. I also don't believe anyone is over emphasising the abilities of the Mosquito; it's hard not to sit up and take notice when its performance and versatility was as good as it was
at that time. This is the key to things; the Mosquito was considered to be far more of a revelation when it was built than how we view it today because of what it offered. These days, a twin engined unarmed bomber with high performance is not such a big thing, but then, that was food for thought and intolerable for many in the RAF Air Staff.
Excitement about its versatility came from the sheer number of roles and how well it could do those jobs compared to other types, and yes, the LW had the Ju 88, but the Mossie could out perform the Ju 88 in almost every respect (Ju 88G-7b max speed 389 mph, ceiling 32,810 ft, climb 500 ft/min, Mossie NF.XV max speed 412 mph, ceiling 43,000 ft, climb 3,500 ft/min - this is not to denigrate the Ju 88, terrific aeroplane), and although later Ju 88 NF performance was equal and sometimes better than the early NF Mossies, the Mossies were doing that performance long before the Ju 88 was.
This is the point; when it entered service, no twin engined fighter or bomber had the outright performance of the type (service aircraft, not prototypes), nor could any other type do the wide range of tasks the Mossie could in the same airframe.
I guess you have to forgive us for expressing how good the Mossie was - and it was no myth that it was that good; its performance and capabilities had no equal in any other aircraft of its size/weight class. Its war record speaks for itself also. I don't think anyone expresses any exaggeration about the Mosquito's performance and abilities because there is no need to, unlike some German types that are regularly discussed here.
