This thread is to examine the aircraft, systems, and networks that were involved in the 'electronic barrier' that was part of the McNamara Line, a defensive line developed to block North Vietnamese and Viet Cong soldiers from accessing South Vietnam along the Ho Chi Minh Trail. The aircraft...

Gonna park this in the Bar for now, if there's a better spot the mods can move it. I'm looking for a good book on PT boat operations in WW2, and a separate book about Swift Boats in Vietnam (I doubt there's one book that covers both). Anyone got some suggestions? Books written by PT or Swift...

Sort of a general topic here, and I hope this is the best spot for it. My question is how one would fix the miserable state that shipbuilding for the USN is in. I've got to assume commercial shipbuilding has suffered greatly as well due to many of the same conditions. It sounds like there aren't...

Hello, Described in both Naval Fighters #75: Grumman F7F Tigercat and F7F Tigercat in Action is a zero-length launch rack for launching the 11.75" Tiny Tim rocket without need for a drop beforehand, developed at NOTS China Lake and intended for the F7F. Evidently it seems it's only for the...

I imagine this probably never got beyond the napkin stage, but very curious if anyone has more detail on this. From a 2006 USNI article by Norman Polmar; https://www.usni.org/magazines/naval-history-magazine/2006/august/atomic-fish The thought of a Silverplate Avenger is moderately amusing.

Watching the decline in size and construction problems encountered by the USN since 1991 I am reminded of the fate of the Royal Navy after WW2. At first sight the US has done rather better. It still has the world's largest force of nuclear strike carriers and its nuclear submarines remain the...

Hello, I have some files from NARA to share. These are a selection of sketches and tables taken mostly during the conference itself in 1930, which were kept in a miscellaneous folder at NARA. There were also battleship and aircraft carrier sketches mixed in the "light cruiser" papers which I...

Late 80s (88-90) US Navy Program to replace the E-3C, S-3B and EA-6B carrier-based AEW, ASW and EW aircraft. I believe it evolved into the E-X program to replace the E-2, this is why i’m attaching the image of the Boeing E-X proposal, which is seen here in ASW markings. (VS-24 scouts was an S-3...

I am looking for technical information on the AN/ARN-92 LORAN-C/D navigation system, particularly for the sketches or photos of the cockpit control unit and display panels if they existed. This system was used, inter alia, on the F-4D, RF-4C and F-105D, and reportedly provided an approximate...
