Can anyone tell me if the following picture is that of an early F119 or a picture of the F120:

This is first-to-fly N22YF, originally equipped with YF-120 engines, but they were replaced with YF119 in USAF Museum.
YF-120 with its VABI still remains a touchy subject.

Thanks flateric. I thought that may be the case as there doesn't seem to be any publically avaliable images of the F120 rear end.
The early F119 engine is quite a bit different to the production model, as this early model doesn't have the radial 'finger' like flameholders. I can see what looks likes a large central gutter/bluff body, with possible spray holes circumferencially placed?

Actually the USAF Museum now displays an actual F-22 S/N 91-4003; not a YF-22 (which was 87-0700/N22YF)

91-4003 - http://www.f-16.net/aircraft-database/F ... file/5506/
87-0700 - http://www.f-16.net/aircraft-database/F ... file/5511/

The engine on display at the museum next to the Raptor is a YF119-PW-100L; which is a 'prototype'. (Hence YF-, not F-)
