Found on the secretprojects forums, some old Nimrod MRA4 promotional artwork. Cancelled due to various issues, the most common one on the internet being some variation of the wings and fuselages not fitting together right. There's a couple variants I've seen, from the old 60s vintage fuselages differing from each other while the new wings were build to a common standard, the new wings not being built to a common standard (unlike in the age of CAD imo), or ye olde tolerance stacking.
It seems to have been less of a complete hash than the AEW3, at least.
