Is the correct answer - probably.

Is that your next project Eric?

The question has to be - why?

Was it not for crop spraying/dressing?

That wasn't the question. Why build THAT particular design?

There were plenty of Soviet designs already in existence that were suitable for crop spraying without cobbling together that mess up.

That reminds me of a joke which I'll adapt for the Galaxy...

So a Galaxy pilot is flying from A to B minding his own business when a fighter jock in an F/A-18 flies past and gets on the radio.
"Hey heavy fella, watch this - I bet you can't beat it"
Fighter jock proceeds to perform his audition display for the Blue Angels.
"Well whaddya think?" says the jock.
Galaxy pilot says: "Pretty fancy but can you do this?"
...flies straight and level for 2 mins...
Fighter jock: "What was that?"
Galaxy pilot "I just got up for a walk to stretch my legs and got coffee and danish*".

It was an early ambition in aviation -

I remember posting up on here that my Dad used to cycle to Bruntingthorpe to watch the JATO B47 take-offs.

I just searched the original post and it was back in 2011.

When 6 engines just aren't enough.

[Eric Mc]

Six definitely wasn't enough with the weedy jet engines available at the time.

The B-47 is one of the most important aircraft designs ever.

Must have been quite a sight.
My Mum grew up in a farmhouse at the end of the runway - she was quite friendly with the base commander's daughter as they were both mad on horse.
She used to comment that it was a ridiculous people complaining about noise from Bruntingthorpe when she compared it to how it was as an operational base...

Swept wing, underslung engines.

Well the Arado 234 takes that for underslung jet engines.

Not really, the Arado engines were directly attached to the wing, not fundamentally different from Meteor or Me262. The difficult bit was putting engines in pods beneath the wing. Tricky aerodynamics to reduce the strain on the supports, but worth it to protect the wing if an engine catches fire.

It's not JUST the fact that it had underslung engines. Lots of aircraft before the B-47 featured those. The Arado Ar234 is a good example, as is the Messerechmitt 262. In fact, an awful lot of piston engined twins and four engined aircraft had underslung engines too.

The swept wing on its own was not revolutionary either. The theory of sweeping wings to help alleviate the compressibility of air near transonic speeds had been known since the 1930s and was being incorporated in other designs before the B-47.

What was revolutionary about the B-47 was the combination of a number of features -

1 - ultra thin wing to assist in achieving a high subsonic cruise speed
2 - sweepback for the same reason
3 - podded underslung engines mounted FORWARD of the leading edge of the wing on pylons

The positioning of the engines on forward raked pylons was done deliberately to allow the wing to be thin.
Swept wings exhibit a number of undesirable aeroelastic twisting effects - chiefly the tendency for the leading edge to want to rotate upwards. One solution to counteract this is to make the wing fairly thick with a deep wing spar. Look at the leading edge of a Vulcan, for instance, or even a Comet.

Boeing wanted a thin wing for performance. They discovered that by hanging the weight of the engines not only under the wing but also a fair bit ahead of the leading edge, you could counteract the twisting motion and retain a thin, lightweight wing.

It was such an elegant solution that most airliners today, over a certain size, use this technique to some extent.
