I will try to find a copy of "AWACS and Hawkeyes" by Edwin Leigh Armistead, MBI Publishing, ISBN 0-7603-1140-4. As for the APS-26 Butterfly and APS-27 Firefly, they were originally developed by the MIT Radiation Laboratory as Project Butterfly and Project Firefly. They were transfered to the...

You are quite correct, Glider. The AN/APS-20-base AEW aircraft we very useful and long-lived. Never meant to imply anything else.

The communication's suite on an aircraft has nothing to do with the on-board radar being an MTI radar or not. It is the guts of the radar which matter; the waveforms(s) transmitted and the processing of the returned signal. If you want to use an AMTI-equipped aircraft in a GCI-type manner...

To Glider for his mention of the AN/APS-20. The delay was caused by the need to do some research. Steeljaw Scribe at Steeljaw Scribe: History of AEW: Project Cadillac II (Part One) states that the AN/APS-20 was the first AEW radar and an AMTI radar. The former is true; the latter is not...

The H2S was also known in the UK as the ASV (Airborne Surface Vessel) Mk VIB. Even earlier versions of the airborne ASV (possibly the Mk I; certainly the Mk II) could detect other aircraft in flight under very favorable conditions. But it did not exploit the movement of those other aircraft...

That is the document which mentions Project Firefly as having developed the AN/APS-27 (from the AN/APS-23), saying "At the end of the war it was operational but had deficiences[sic]". No mention of a TBM in that paragraph but I could certainly believe it was fielded on one. They seemed popular...

According to multiple sources, the first AMTI (airborne moving target indicator) radar, admittedly a noncoherent implementation, was operational by the end of WW II. On source identifies it as the AN/APS-27, an airborne search radar developed by the MIT Radiation Laboratory under the name...
