Recent pic? No. That Buff sits at the Pima Air museum now. Was mistaken. This was another B-52 doing an engine test for the type they hang on the 747. There are other pictures of another B-52 with a C-5 engine in the same position. |

Would the outboard engines drag on landing?

How many times if ever have there been engine upgrade / replacement programs for the Buff? There presumably have been a few over the lifetime of the program as engine technology has evolved.

The B52H last built in 1962 had the JT3D turbofan engine (previous versions were turbojets). No upgrades since then although several were proposed but not funded. |

They might have to put the outboard engines on top of the wings.

Given some of the most recent proposals, a re-engined B-52 might look a lot like the current B-52 configuration, with eight CF34s in place of the P&W TF33s.
*** by Bill Sweetman Aviation Week 10-Oct-2014 The U.S. Air Force is reviewing industry studies of fitting its 50-year-old Boeing B-52 bombers with new commercial-derivative engines, according to Lt. Gen. Stephen Wilson, commander of the service’s Global Strike Command. So far, Wilson said Oct. 9 at a Washington meeting, the Air Force assesses that the change would result in a net cost savings over the remaining life of the B-52s, which are expected to fly until 2040. Wilson did not identify the contractor that made the proposal or whether more than one company is involved. However, an industry source confirms that Boeing has presented a "concept brief” and that General Electric has looked at fitting the bomber with eight CF34-10 engines. Pratt & Whitney also is exploring options. . . . GE’s eight-CF34-10 option could deliver more thrust than the current engines (variants are rated at 17,640-20,360-lb. thrust) and would avoid engine-out handling issues. *** Complete Article Linked at Title *** Using paired CF34s wouldn't be as radical concept as it might initially seem. The E-3 was originally intended to be powered by eight TF34s paired on four pylons. |

Until 2040...
Those guys did something right. How many ships are still in service from when those planes were made? |

The biggest problem is control with an engine out. With eight, it's not a problem. If you hang four really big ones out there and loose two on one side, the adverse yaw might be more than the flight controls can control.

I see the old Bears still have a tailgun. Realize it's pretty useless in the modern era, but I think it's cool, regardless.

I wonder how the protocol works with this, do the fatigued Russian pilots just look over and all of a sudden see the giant F22 sitting off their wing or is there communication that lets them know that we're coming? 
ETA: I think I missed the joke
