The VT Fuze: The Other Secret Weapon of World War II

Friday, September 11, 2015 9:16 AM


USNI VT fuze.

As a young officer, then-Lieutenant Commander (later Admiral) W.H. P. Blandy, USN, had a keen interest in gunnery. Writing for Proceedings in 1920 (“Director Fire a Century Ago”) and 1925 (“Possible Improvements in our Gunnery Training”), LCDR Blandy understood well the history of fire control and what could be done to improve its effectiveness. Ever forward-thinking, Blandy noted elsewhere in 1925 of what a remarkable device a fuze that would detonate based on its proximity to the target would be. The key would be to find a way to trigger the shell to that its fragmentation pattern would be effective,… Read the rest of this entry »

Driving Navy Innovation: Turboelectric to Hybrid Propulsion

Monday, March 23, 2015 4:39 PM


By Rear Adm. Kevin Slates Director, Energy and Environmental Readiness Division Ninety-eight years ago today, the Navy deployed a new technology onĀ USS New Mexico (BB 40) that was then hailed as one of the most important achievements of the scientific age: the turboelectric drive. Before this major event, ships used a direct-drive steam turbine, which started with the HMS Dreadnought. Direct drive turbines were very efficient at faster speeds, but at slow speeds they wasted energy when the propeller turned too quickly, causing cavitation. Since the average underway speed of battleships was under 15 knots, this proved to be an… Read the rest of this entry »

Frogmen in the 1950s

Friday, October 22, 2010 10:20 PM


Here’s a snippet of history from Navy TV – a 1959 newsreel about Navy Frogmen, that demonstrates a long-endurance dive by Underwater Demolition Team “frogmen” who stayed underwater for a record 48 hours. Yes, dated and funny! And another one -about the UDTs (the precursor to the Seals) this is supposed to be a recruiting film – makes you think twice!! Hell Week, the Tower – the whole 1957 Underwater Demolition Team training. Dated, but exhausting.
