Some day, I just gotta do a model of a B-52 with warp nacelles under them. you mean like this?
I also think that capital investment money such as new engines would detract from investment in new bomber projects.
no idea who made it, but i found the image ages ago..
...Might wanna check with the forum over at Starship Modeler, as ISTR this one showing up on .history - Pat Flannery may have posted the link to the image - right about the time Polar Lights released their 1:1000-scale TOS Enterprise kit. The engines are supposed to be 2nd Pilot nacelles, which means the spike on the bussard domes, and the "pinholes" in the exhaust ports. A couple of the modelers on .history were talking about making similar kitbashes with the YF-12A and B-58 kits, but I never did see anything come about from those ideas.
...Heh, replace the engines on a Hughes H-4 with the PL nacelles, and the pontoons with the ones from the AMT 18" kit, and imagine the wake left behind as the plane reaches takeoff speed
No re-engining program so far and probably never.
...Never say never where the BUFFs are concerned, When I first enrolled in NROTC, we had one of the Air Farce types give an open lecture on air superiority, and during the lecture he predicted that "by 1990 the Pentagon will put out the first call for proposals for a 'multi-role' new-tech bomber to replace the B-52s by the end of the century." Of course, this was several years before Jack Northrup was vindicated and the B-2 was declassified. Then, in 1991, See-BS News did a short segment on the "aging B-52" fleet, and how they were all going to be refurbished to last "until 2010, when they'd be gradually phased out and replaced with newer Stealth bombers that will replace the B-2's."
...It's 2011 now, the Evil Soviet Empire is gone, there's no 24/7 sorties and Fail-Safe points, and there's damned sure no B-3 Super Stealths no matter what the Groom Lake Watchdogs claim. The B-52 is still our major bomber component, all the BUFFs are about to get their cockpits glassed, their cables fibered, their wings tweaked, the tires checked, and maybe even MP3 players in their custom-designed toilets. Hell, they may even get magnetic "Gulf Kick In Your Gas Tank" magnetic horseshoes to put next to the fuel inlets. Add a coating of Turtle Wax, and the B-52s will probably last well into the third quarter of the 21st century. Which is why I wouldn't rule out the possibility of an engine swapout to a more fuel-efficient design sometime after 2030 to 2040 at the latest.
Most of us old guys won't see this happen, but hopefully this forum will live long enough to see my prediction come to pass...
