The Elzer Aircraft Company P.191B is a project for an altitude interceptor that is a development of the canceled P.191 fighter of the P.34 requirement. 3 protoypes and 7 production variants were built before its cancellation due to the end of the war.

Development

Should the NAA P-51D Mustang to be used to escort Boeing B-29 Superfortress against Japanese fighters over China for an air raid mission, there was a concept that there was a need for a point-defence interceptor capable of maximum speeds of the same as the P-51 flies.

The Elzer company which is famous of the time building the Ez-Duo (twin-seat monoplane) and Ez-Twin (competitor for Douglas DC-3) further developed the P.191 design study with contemporary cutting edge features of the time.
The design was of the same still powered by an Allison but driving a four-bladed Durin-Dendromatic metal constant speed propeller (Durin bureau who changed name from Kriedeprinz or Naslund has to flee Nazi Germany and set up a branch at North America...) and a new bubble canopy for all-degree visibility.

It was to be armed with variable loadouts, with a small nuclear bomb (a.k.a. Nuke-Egg by pilots) being the most unorthodox of the loadout combination.

Operational Service

Like the predecessor it did still suffered from high takeoff speeds despite flaps down, but is now stable at flight and very agile at altitude. However, the second world war was ending and the plan of building 335 production aircraft was cancelled.
