I have just seen three Canberra PR9s flying in formation over my house.
I live not far from RAF Marham (in fact, I used to serve there a number of years ago), RAF Lakenheath and RAF Mildenhall (the latter two are USAFE bases) and so I'm used to seeing military aircraft.
There was an article a couple of weeks back in the local newspaper about 39 Sqn at Marham. They had just completed their final operational mission over Afghanistan and were preparing for disbandment. I reckon that those three Canberras that I've just seen are the last airworthy ones in the RAF. After hearing about all the problems that they have had with them over the last few years, I'm amazed that they managed to get three serviceable at once!
The Canberra PR9 is a strategic reconnaissance aircraft - the last one that the RAF has. It will be withdrawn without being replaced. There is a lot of that going around in the British armed forces these days. The Sea Harrier F/A2 has recently been withdrawn from service, to be replaced by the Harrier GR9. However, the GR9 has no radar and no offensive air-to-air capability and so British fleet units now have no in-depth air-defence. This situation will remain until the F-35 is brought into service in 2017. Did I say "until"? I meant "if". And it's a big "if".
Look at the situation with the Eurofighter Typhoon. The Typhoon was supposed to be in service by 1998. Eight years later and it is only just coming into squadron service. However the jet is so unreliable as to be operationally useless. So severe were the problems that the Operational Conversion Unit had to based at Warton, the manufacturer's airfield, for a year. Typhoon is now in service, but the maintainance man-hours required to keep the thing in the air are significantly higher than that required by the Jaguar, a 30 year old jet which the Typhoon has replaced. Add to that the problem that the Typhoon isn't yet cleared for the release of air-to-ground stores and we can see that it's not exactly a viable Jaguar replacement, is it?
I worry about the future of the British armed forces. In the meantime, it was nice to see some Canberras in flight - maybe for the last time. At least they were quiet! ;-)
