This Navy testbed is a very fast – and “sharp” – ship

Believe it or not, the United States Navy has a very fast testbed vessel — one that not only looks futuristic, but is also being used to test all sorts of futuristic technology. That vessel is known as the Stiletto, and while it looks like something out of science fiction, it's actually 13 years old.

When you look at the Stiletto, your first impression, based on its shape, is that it's some sort of stealthy vessel. That's a common misconception. During a tour at the Navy League's SeaAirSpace 2018 expo in National Harbor, Maryland, members of the Stiletto program explained that the ship's radar cross section is about what you'd expect for a ship of its size.

The Stiletto's hull is made from carbon-fiber composites.

The ship looks as it does because it has a carbon-fiber hull. The material is incredibly light — I had the opportunity to handle a roughly softball-sized chunk of the material and can tell you first-hand. While the exterior is durable (the ship has handled seas rough enough to make lab-acclimated scientists queasy), it's also vulnerable to being punctured.

According to an official handout, the Stiletto has a top speed of 47 knots. However, during builders' trials, the crew reported hitting a speed of 54 knots. Normally, the ship cruises along at a comfortable 30 knots and can go 750 nautical miles on one tank of fuel.

In addition to being able to carry a RHIB, the Stiletto can also launch drones.

But the Stiletto also has ample space – it easily accommodated a rigid-hull inflatable boat that was over 30 feet in length, and there was still plenty of space left over for other gear. The crew explained that adding new systems to the adaptable ship takes a few hours or a day at most.

The wide array of sensors on the Stiletto show how easy it is to add something new to try out.

One thing that was skimpy on the Stiletto, however, was the galley, which consisted of a microwave oven and stack of paper plates. The ship of the future, it seems, didn't quite have everything.

4 critical components to the success of the first total penis transplant

The procedure was performed on an Afghanistan war veteran wounded by an IED

Doctors at the Johns Hopkins University School of Medicine in Maryland announced the first-ever successful total penis and scrotum transplant was performed on an Afghanistan veteran recently. The recipient was wounded in an IED attack that left him without sexual or urinary function but left his internal organs unharmed.

The procedure was performed on March 26th and the unidentified "sergeant" will have urinary function by the end of the week.

How R. Lee Ermey's Hollywood break is an inspiration to us all

While there have been many outstanding actors and celebrities who have raised their right hand, there has never been a veteran who could finger point his way to the top of Hollywood stardom quite like the late great Gunnery Sergeant R. Lee Ermey.

Marines used a 3D printed F-35 replacement part for the first time

Marines with Combat Logistic Battalion 31, 31st Marine Expeditionary Unit, are now capable of "additive manufacturing," also known as 3-D printing.

This innovative process uses 3-D printing software to break down a digital model into layers that can be reproduced by the printer. The printer then builds the model from the ground up, layer by layer, creating a tangible object.

History

The 'indomitable determination' of John Paul Jones lives on in the Navy

April is a great month to remember the namesake of one of our Pearl Harbor guided-missile destroyers, USS John Paul Jones, named for a founding hero of our Navy and proudly known by the crew and their families and friends as "JPJ."

On April 19, 1775, the Battles of Lexington and Concord lit the match of Revolution against British tyranny. At the time Great Britain had more than 250 warships with nearly half having 50 or more guns – cannons. Our tiny naval force consisted of a few ragtag privateers and some humble sailing vessels. Even before our nation began, the founders commissioned 13 frigates and recruited warfighters, including immigrants like John Paul Jones.

This is how the 'missing man formation' honors fallen pilots

The first time I witnessed a 'missing man formation' was at the funeral of my grandfather, who flew the B-25 Mitchell during World War II. After his service in the Army Air Corps, he became a commercial pilot for TWA and then ventured into private flight. He died in an airplane crash at the age of 74 and my family gathered with his aviation community at Santa Paula Airport for his memorial.

At the ceremony, we looked to the sky as a group of planes from the Condor Squadron flew overhead. One of the planes banked away, leaving an empty space in the formation.

The symbolism was not lost on me.

This Army vet started a supplement company dedicated to education

Before John Klipstein joined the Army, he smoked a pack a day and his PT test run time was roughly 23 minutes — which accounts for the time spent throwing up on the side of the track. The military turned that around. The newly-minted 13B found a love for fitness and pushing his body to the limit. After leaving the military, he developed a line of supplements to help others do the same — safely.

Taiwan is ready to push back against China's aggression

Tensions between the Peoples Republic of China and Taiwan have recently flared up as China held the largest show of naval force in its history in April 2018, and made new threats directed towards Taipei.

"We would like to reaffirm that we have strong determination, confidence and capability to destroy any type of 'Taiwan independence' scheme in order to safeguard the country's sovereignty and territorial integrity," Ma Xiaoguang, a spokeswoman for the State Council's Taiwan Affairs Office, recently said.

The president is getting a new Marine One after almost 60 years

Marine One is an icon of the presidency and for the most part, one helicopter has carried that load for almost 60 years: The VH-3, which first carried President Eisenhower in 1961. The current D model of the VH-3 entered service in 1978 and was later backed up with the introduction of the VH-60N in 1987. But, the fact remains that both of these helicopters are getting older by the day.
