Viper Mk204 - Myth or Fable?
I know you guys are good, but this is one of those "always wanted to ask" questions that is a bit of a stretch.
The Armstrong Siddeley Viper engine was a nifty piece of kit, starting out as an ultra short life expendable target drone engine and eventually becoming a surprisingly reliable turbojet on many aircraft perhaps most notably the various versions of the JP.
The Mk202 version was installed in the T4 and T5, but there was a suggestion that the Mk204 was specifically designed with enhanced safety and durability features and installed exclusively in JPs that were used by HRH during his flying training.
Like I said, bit of a stretch but I figured that if anyone knew he would be on Pprune.

Mk.204 Evidence found on a surviving Mk204 engine suggests this is a Mk202 variant with increased temperature and oil pressure transmission capabilities. These are thought to be safety measures installed for use in Jet Provost aircraft used by HRH Prince Charles during his Royal Air Force flight training programme.
Chevvron: Time - expired airframes, I believe. They were heavily used due to their 'sportiness'. I know some have flown in private hands, but one assumes those to be few in number & not viable to be maintained as a service fleet.
Anyone know if any are still flying?

Airworthy JPs in the USA
There are at least 2 x T4 in the USA that might still be flying:
N219JP - former XS219 in camo scheme - has an Experimental certificate valid to 31 Oct 18.
FAA Registry - Aircraft - N-Number Inquiry
N547XP - former XP547 in grey scheme - has an Experimental certificate valid to 31 Jul 17. It was all grey on 79 Sqn TWU until wfu.

In addition, there is a very smart red/white/blue T3 that has an Experimental certificate valid to 31 Jul 17 that was at the Aviation Nation 2012 and 2013 shows at Nellis AFB:

There are also numerous other T5 and T5As:
FAA Registry - Aircraft - Make / Model Inquiry

Strange, one would have thought it would nave been more prudent to have updated the brakes for him given his (off) track record

Viper Mk204
Just spotted this thread......as has been noted there is indeed a Mk204 Viper, alive and well, currently installed in Jet Provost XS186 at Metheringham in Lincolnshire.
We have been running the engine (and operating XS186 in a taxiable condition) since 2010 and, Covona-19 dependant, we will continue to do so.
For more details,see:

Thank you for that picture, relight. It's now my wallpaper, replacing a Vampire that has been there for many years. The closest I got was 183, a 2 FTS airframe, based at Syerston in '66.

Wow! You guys have done a brilliant job there. I volunteer at the Cosford museum, and I see the work the team does there, just to keep the exhibits in display condition. I'm hoping to be Skegness way once this virus is sorted. I'll keep an eye on your website.

Let me know if you’re in our area any Saturday and we’ll put the kettle on (again).
