USAF Fund B-52 Engine Replacement
Have you ever heard of the Gulf War? Look it up.
I'll help...During Desert Storm, the B-52Gs completed approximately 1620 sorties. In fact, the B-52s managed to drop almost a third of the entire tonnage of bombs dropped by US aircraft. No B-52Gs were officially reported as having been lost as a result of enemy action during Desert Storm. However, several were damaged. One B-52G was damaged by a hit from an unknown type of missile, but was able to make it home safely. Another lost a couple of engines as a result of a near-miss by a SA-3 missile, whereas another was damaged by shrapnel from AAA fire. One B-52G (58-0248) was even damaged by a hit from an AGM-88A HARM missile fired by another US aircraft that was providing defense suppression support for the attacking force. The missile managed to home in on the tail-mounted gun-laying radar of the B-52G, and obliterated a sizeable chunk of the tail when it hit. Fortunately, the damaged B-52G was able to land safely at Jeddah and was sent to Guam for repair. One B-52G (59-2593) was lost on February 3, 1991. The cause of the loss was officially blamed on a catastrophic electrical system failure while returning to its base at Diego Garcia, but there are rumors going around that combat damage was actually responsible. Three of the crewmembers ejected safely before the aircraft crashed into the Indian Ocean, but three others ejected too late and were killed.

I would call that combat, and other conflicts since.
Colonel Ramsay bio
In January 1991 he was the flight leader for the first night, low-level combat mission ever flown by a B-52G, leading 14 aircraft to strike five Iraqi airfields in the opening minutes of Operation Desert Storm.
On 17 January 1991, seven B-52Gs, known as the "Doom Flight", took off from Barksdale AFB in Louisiana to help kick off the air campaign. They performed a flight that lasted 35 hours and took them almost halfway around the world to launch 35 CALCMs and then go back home. The routes of the missiles were planned so that they would impact almost simultaneously, and 33 of them hit their assigned targets. That same day, the B-52G followed up this strike with the first low-level attacks conducted by the type after decades of training. Buffs swept into Iraqi airspace at an altitude of 90 meters (300 feet) to pound four airbases and a highway.
With Iraqi air defenses disabled, the B-52Gs then returned to high-altitude bombing, with three-ship formations pounding Iraqi troops concentrations in Iraq with 340 kilogram (750 pound) bombs and cluster bombs. The B-52 performed 1,600 sorties in the Gulf War and dropped 22,725 tonnes (25,000 tons) of munitions.

Remember this is a swing-wing airplane. There are some massive, monolithic, fracture critical structural components that are flight critical. Even if they had saved the production tooling (which they didn't) repairing/replacing those structures is just not feasible. A lot of money has been spent and a whole bunch of very smart engineers have been working for over a decade to crack this nut. They've found that it would cost more to fix than it did to build, and even then, the final result is shaky at best.

Actually, yes, they have looked at that. Modern FADEC engines are essentially self-contained. They're not dependent on aircraft systems (like air data computer outputs) for their operation. Obviously they need an electronic connection with the cockpit for throttle position, but that's about it. And that can be done on a databus. That same databus can provide the cockpit with engine operating parameters (EPR, N1, N2, TIT, fuel flow, etc). And the Buff has already received a fairly extensive avionics upgrade to make it GATM compliant, plus the fleet is now being upgraded with the Boeing CONECT digital communications upgrade which includes an extensive onboard high-bandwidth, rad-hard and EMP-hard digital databus. The Buff is by no means all analog. CONECT is open architecture, so expansions and upgrades were specifically designed to be (relatively) easy.

B-52'S Keep Them Flying.
Hello All
The B-52 has been one of my favourite aircraft for a long time. With the different upgrades & modifications I hope they will be flying for another 30 years or so.
Cheers

Having seen the B-52 contrails heading north, I used to wonder what the Republican Guard thought. They knew that they would most likely soon be desert hamburger and there wasn't a thing they could do to stop it - except to surrender.

Not much you can do - hope they're going to hit someone else, hope they miss...
But it always astounds me how many people seem to have survived a carpet bombing attack over the last 80 years

yes but if they'rre trained and bloody minded they can still stop an advance - rather like the episodes in WW1 and the US Civil War when people exploded bloody great mines under the opposition front line.
In most cases someone (normally an NCO) rallied the survivors and reoccupied the devastated area in time to slow or stop the oncoming attackers... Also several occurrences in Normandy in '44.... and we won't mention Casino ................

USAF likely to issue B-52 engine replacement request for proposals in early 2019
The US Air Force is likely to issue a request for proposal for its Boeing B-52H Stratofortress bomber engine replacement programme close to the first quarter of 2019, according to an Air Force document released on 13 March.
The contract for re-engining the USAF’s 76 Boeing B-52H bombers would likely be granted some four to six months after final proposals are submitted, according to the document. The department is looking to acquire at least 608 new, commercially available turbofan engines to replace the eight Pratt & Whitney TF33s each bomber carries.......

Does each B-52 really need 608 new engines? That's a lotta new engines...
So 76 B-52H models going forward? I seem to recall around 42 being combat coded, a few dozen more with various reserve/attrition coding, and about 90+ H still intact, with 12 still at AMARC in 1000/inviolate storage (with GhostRider escaping a few years ago, the only B-52 to date to do so). I note the pondered order is for at least 608 engines, but would imagine another 10-20% for spares? An impressive order indeed.

But they were still alive Ken... which is my original point... carpet bombing (or mining) doesn't wipe out all opposition.... I doubt the Wermacht or the Confederacy would have surrendered in droves...
