Érase una vez sólo dos bandos (y sabías qué esperar) y había un país llamado Unión Soviética. Y el portaaviones era la especie dominante en los mares (Cuanto más grande era el portaaviones, más felices eran los almirantes), pero este tipo de barcos son muy caros, tan caros que parecía que iban a...

From 1979 to 1980, the United States Navy proposed updating their remaining obsolete FRAM Gearing class destroyers in the Naval Reserve Force as escorts to protect trans-Atlantic convoys against Soviet submarines. Some of the proposed modernization included replacing the WWII-era 5"/38 twin-gun...

The study of old aircraft manuals and Standard Aircraft Characteristics (SAC) can bring interesting conclusions. These documents listed avionics setups of the aircraft, and may bring surprising conclusions. The US Navy aircraft did not have too much on-board electronics, only very essential...

I read in Friedman's US cruisers book that it was proposed to modernize the Omahas by replacing their guns with 152mm/47s, among other things. Also, I found from another source a proposal to convert the class to AA cruisers: "In 1940, a project was developed to convert Omaha-class cruisers into...

White there is information about the missile itself: https://www.designation-systems.net/dusrm/m-84.html https://www.docdroid.com/WbANE9i/agm-84-harpoon-missile-block-1d-brochure-pdf#page=2 There are mentions that, one of the reason it wasn't produced, was that the missiles were too big for...

*Apologies if this is the wrong section, please feel free to move if appropriate. While doing a bit of research on the FFX frigate program (the one from the 80s), I accidentally stumbled into an old FAS page detailing the "1988 Surface Combatants Force Requirements Study", which provides a...

Chciałbym dokonać porównania tych dwóch okrętów podwodnych. Mam na myśli system sonarowy, technologię akustyczną, szybkość i ogólne porównanie technologii. Chciałbym również wiedzieć, co jest niesamowitego w ssn 790 South Dakota, że wszyscy piszą o pewnej przewadze akustycznej nad innymi...

I would like to make a comparison of these two submarines. I mean sonar system, acoustic technology , speed and overall technology comparison. I would also like to know what is amazing about ssn 790 south dakota that everyone writes about some acoustic advantage over other subs.

After reading the JPL paper on the radar, I learned that the prototype radar employed 3700 travelling wave tube amplifiers. Judging from the diagrams in the paper, it looks as if each radiating element had a dedicated amplifier, just like in an AESA radar: This sketch from the Russian...

The book American Secret Projects: US Airlifters Since 1962 describes in detail the Model 2007 carrier on-board delivery aircraft project, which was basically a scaled-down Model 1906A with a swing-tail loading arrangement. Two versions of the Model 2007 were envisaged, the four-engine Model...

Author's Note: This is a timeline that I've been working on that explores a different Cold War where the United States Navy is forced to maintain a larger carrier fleet, one that the Essex class continues to play a large role in. The first few posts won't focus on the class themselves, but are...

From Grumman Aircraft since 1929, here is a Grumman designs 137,142,165 and 215,all develop from S2,and remained a Projects.

Just posted by the San Diego Air & Space Museum at YouTube, test footage of the Teledyne Ryan Model 262 Manta Ray. The Model 262 was conceived for the US Navy's Ship Tactical Airborne RPV (STAR) program in the 1970s (hence the "Ryan STAR UAV Test" title at YouTube.) The Model 262 was powered...

There is a reference in Norman Friedman's "U.S. Amphibious Ships" to a canceled 225 ft. ocean minesweeper that was related to the singleton unit USS Carronade in terms of hull form. Aluminum hull construction would have made a great deal of sense as it was very obviously amagnetic and less...

From DefenseImagery.mil, an artist's concept of the Bell Aerospace Textron Mine Sweeper Hunter (MSH). In Fiscal Year 1984, the US Navy embarked upon a program to construct 17 minesweeper hunters of some 470 tons displacement that utilized surface-effect-ship and glass-reinforced plastic hull...
