How about a 737 based mini-tanker?
Actually doable, a history of the 737 design states that the necessary provisions are there.  Perhaps just three drogue spots (fuselage and under each wing) rather than with a boom.  I wonder how a 727 tanker would fare?

I recall there was some interest in the late 90s early 2000s in a small tactical tanker that would actually also serve as a C3I node and possibly as a stand off jammer as well as a tanker in support of strike packages.  Rumour had it that Lockheed was working on something stealthy/sneaky off the books to fill the role but if it had existed and the high end stealthy version had been cancelled there could be a whiffie justification for a non stealthy 737 doing the job.

Thanks, that's not the article I read and it is far more informative.  I wasn't aware they had actually gotten as far as a proposal, sort of looks like a Gulfstream doesn't it?

Boeing NT-43A Radar Test Bed

The Air Force operates a modified NT-43A as a Radar Test Bed (RTB) with radar imaging gear on its nose and tail in radomes that are 9 feet long and over 6.5 feet in diameter.

Hmmm....I wonder how one would go crossing a 737 with a Nimrod AEW3:

Basically cross this:

Found this via Facebook:

Coulson Aviation is adding not only additional air tankers to their fleet, but is branching out into a different model of aircraft. The company has purchased six 737-300’s and intends to convert them into 4,000-gallon “Fireliner” air tankers. Britt Coulson said they saw an opportunity when Southwest Airlines made a decision to replace their 737-300’s with the new 737-Max. Since the FAA only allows Southwest pilots to fly two of the 737’s with the same rating, the airline opted to sell the 737-300’s even though they have a relatively low number of hours in the sky.

No images of final conversion.

Photo's of the prototype. Tanks are not yet installed.







I think they missed a great opportunity to paint the cool looking black anti-glare panels that TCA had on their Vanguards and DC-8s and 9's.

Random idea:  VTOL 737 based on similar concept to HS.141 commuter airliner:

In reference to Robert's recent purchase of the BPK 737-200, I have the T-43 boxing.



It will be finished as a CAF CE-43A. I will be taking a nose from the Amtech EC-135N/E ARIA/ALOTS "Snoopy".

A 4 engined 737?!  Boeing/Kawasaki 737-PXL: 



This was a joint venture between Boeing and Kawasaki to build a 4-engined maritime patrol aircraft for the Japan Maritime Self-Defense Force. It was proposed in 1974 to replace the Kawasaki's licensed P-2 "Neptune" but Japan chose the Lockheed P-3C "Orion." and in 1977 Kawasaki began producing P-3C under license. The PXL was to have four 9,280lb, GE TF34 engines and a MTOW of 120,000Lbs with fuel of 5,270USG wing tanks and 1,250USG centre tank.

The illustration shows an extended and lowered nose radome and wing tip booms which are possibly MAD probes or other antennae.

It could be built in 1/72 using the BPK kit and engines from a pair of S-3s.

This is getting a bit close to a project I've got in the planning stage. But I'm thinking of a shoulder wing 737 using four A-10 nacelles (same engine as the S-3s) as a military transport. I was a bit surprised to read that for both these aircraft, the engines are rated at a little bit more that 9000lbt, whereas the civilian version of it is rated at 17,000lbt

I don't think the US military ever had the real need, or cash, to develop uprated versions of the A-10 or S-3 engines.  For what you are proposing, I could see an uprated version that fit the same envelope being developed as part of the transport design.  For purposes of a tactical transport, the A-10 nacelle would be the preferred choice as it should have a lower IR signature than the S-3's nacelle.
