This is how Navy SEALs swim out of a submerged submarineDaniel Brown
While the initial development of VR gear and software is expensive, in the long run it's much more cost effective than putting soldiers into real vehicles or physically simulated situations. VR technology also has other potential applications that can make military activities safer. That's why ...
11 In the past two years, this market segment has seen a rise in the number of new players because it offers a competitive entry point with products that are much smaller than manned warships and submarines. The in-service fleet of unmanned naval systems is growi...

Navy submarine expert Charles "Swede" Momsen had the brilliant idea to use a diving bell to carry rescue sailors down to the sub. A diving bell has a heavy platform attached to a bell-shaped cover. The bell is stabilized so it doesn't tilt, creating an airtight pocket of oxygen. Once ...
Fulton's plan was to hammer a spike from the metal conning tower into the bottom of a targeted ship. A time-released mine attached to the spike was designed to explode once the submarine was out of range. Although the system worked in the trials, British warships were much faster than ...
the civilian signal was intentionally degraded for national security purposes. But that changed in 2000 when President Bill Clinton ordered the degradation turned off, making civilian GPS much more accurate. The decision has helped GPS become a more reliable tool for private citizens all over the wo...
With modest overlapping coverage from two or three such satellites, these systems could deliver gigabit-class service to tens of thousands of dispersed households without (much) oversubscription, even assuming relatively high concurrency and usage. Considering this, there seems little doubt that an LEO...
If you owe “too much” you may have to pay a penalty for “underpayment of estimated tax.” Most taxpayers avoid this penalty if they owe less than $1,000 in tax or paid withholding and estimated tax of at least 90% of the current year’s tax or 100% of the tax shown on the ...
Our adversaries are extraordinarily adept at propaganda and public manipulation. And so far, we've been essentially powerless to stop them. This is a continuing trend. And it's yet another example of how a foe with a "flat" structure, like ISIS, moves much faster and more effectively than...
