Projectiles, such as bullets can "blow up" when velocities get high, even high powered rifles shooting light bullets sometimes have those bullets "blow up" and fragment, limiting penetration and terminal effectiveness.
In the same way the rail gun electromagnetically accelerates the shell at 30,000 Gs which is unheard of ballistics with powder, so the concern was that the projectile would fragment and not penetrate the heavy armor it was designed to pierce for a kill.
An example is when shooting hardened concrete with a 35 to 40 grain 5.56 at around 3000 fps+ the bullet blows up and "splatters" on the surface of the concrete, rather that penetrating, or even taking out chunks of concrete. I would imagine then if you took an elephant round of a solid 400 to 500 grain bullet at 1800 to 2000 fps, you would at least be tearing out chunks of concrete, and might even eventually breach that concrete if you continued to hammer that concrete at the same site.
The significance of the snow provides a range of temperatures for operations, as high or low temps often degrade terminal performance of a weapon?
"During the December test firings, the projectiles not only survived and operated under the 30,000 G-force and multi-Tesla magnetic field launch conditions, but performed under ambient operating temperatures ranging between 20 and 60 degrees Fahrenheit, with up to 4 inches of snow on the ground, and with wind conditions ranging from 10 to 50 knots."
what's the connection between 30 thousand g and snow on the ground please?

thanks, I must be inept as I can only repeat my question
it just happened snow was on the ground during the tests, or, alas, the influence of snow upon impact was tested LOL or ... or ...?
...
So they are illustrating the varying conditions had little effect on the weapon/projectile, and that is supposed to make us "feel real good?". LOL
Gotta love the little nuke sign on the radome
Saudi deal sustains Sikorsky MH-60R production
Saudi Arabia’s purchase of 10 Sikorsky MH-60R Seahawk anti-submarine helicopters “dovetails nicely” with delivery of the last of 280 examples to the US Navy, according to the brand’s new parent Lockheed Martin, particularly as production of Australian and Danish “Romeos” concludes.
Sikorsky clinched the Saudi contract for 10 green aircraft last month, seven months after the foreign military case worth an estimated $1.9 billion was approved by the US government.
Speaking to reporters in Washington on 11 January, Lockheed’s director of MH-60R business development Mike Fralen confirms that initial deliveries of the torpedo-toting maritime helicopter to Saudi Arabia begin in 2018.
That schedule aligns favourably with final delivery to the US Navy in 2018, with 217 of 278 production models already received by the service.
The last seven Australian MH-60Rs will be received by the Royal Australian Navy in 2016, concluding the 2011 deal for 24 aircraft — seven of which support training.
Two initial Royal Danish Air Force MH-60Rs have been completed, and were procedurally signed over to the US Navy in October as crew training gets underway at Naval Station Mayport in Florida.
Fralen confirms that six Danish examples will be delivered through 2016, putting the programme ahead of the stated 2018 completion date, with one remaining Danish tail number expected in 2017.
Opportunities for export of advanced anti-submarine warfare capabilities currently abound despite a bleak outlook previously for the Romeo, particularly in the Asia-Pacific region where sabre-rattling over territories has navies on high alert. This security climate gives Lockheed confidence of continued export success for the type, first delivered in 2005.
“The MH-60R is currently being considered by other countries, and we’ll look to see how their analysis and contract decisions mature over the next one to two years,” he says. “Over the next three years, we’ll look at what other countries want to add to their capabilities, then we’ll look at that production time line.”
Sikorsky finishes the S-70/H-60 derivatives in Stratford, Connecticut while Lockheed outfits the final product in Owego, New York.
Lockheed, which supplies the submarine-hunting mission systems, acquired Sikorsky in November, and is now leading the global sales push against competitors such as the anti-submarine-warfare-configured NHIndustries NH90 and Airbus Helicopters AS565.
There are outstanding MH-60R cases with South Korea, with eight aircraft approved by the US in 2012, and Qatar – 10 approved in 2013. Other interested parties reportedly include Taiwan.
Armed with Lockheed Hellfire missiles, Raytheon torpedoes and guided rockets for the Saudis, the MH-60R also comes equipped with advanced radar, deep-water sonar, forward-looking infrared and electronic protection systems, with full-mission simulators and training provided by CAE. It replaces the SH-60B and SH-60F for the US Navy.
source:The U.S. Navy and Missile Defense Agency (MDA) certified the latest evolution of the Aegis Combat System – called Baseline 9.C1 – for the U.S. destroyer fleet. The Aegis baseline, built by Lockheed Martin offers advanced defense capabilities and enhanced integration with other systems external to the ship.
“The Aegis Combat System Baseline 9.C1 offers unprecedented capabilities, including simultaneous air and ballistic missile defense,” said Jim Sheridan, Lockheed Martin director of Aegis programs. “This Aegis baseline also improves Aegis networking capabilities, allowing Aegis vessels to automatically coordinate defense with input from satellite and ground-based radar assets—forming a true shield of defense over a wide area.”
Baseline 9.C1, also includes the most current generation of ballistic missile defense programming, known as BMD 5.0 Capability Upgrade, which offers the proven capability to shoot down ballistic missiles in both the exo-atmosphere (upper atmosphere) and endo-atmosphere (lower atmosphere). The BMD capabilities of Baseline 9.C1 are also present in Aegis Ashore, the ground-based missile defense program that is the second phase of the U.S. Phased Adaptive Approach to protect Europe from ballistic missile attack.
Over the summer, the U.S. Navy and MDA conducted the Multi-Mission Warfare (MMW) tests to verify performance of recent BMD upgrades and are a critical part of the baseline certification process. Over the course of the four test events aboard USS John Paul Jones (DDG 53), Aegis flawlessly detected, tracked, and engaged two Ballistic Missile and two air warfare targets. Each event resulted in the successful intercept of a single target.
Aegis Baseline 9.C1 provides the U.S. Navy surface fleet with the most advanced air defense capability ever. Under this baseline configuration, Aegis merges BMD and anti-air warfare into its Integrated Air and Missile Defense (IAMD) capability using commercial-off-the-shelf and open architecture technologies.
The central component of the Lockheed Martin-developed Aegis BMD Combat System is the SPY-1 radar, deployed on more than 100 ships worldwide — the most widely fielded naval phased array radar in the world. SPY-1 capability has been greatly enhanced with the introduction of a new Multi-Mission Signal Processor (MMSP). Baseline 9.C1 improves radar resolution and discrimination abilities.
As the Aegis Combat Systems Engineering Agent, Lockheed Martin leads the ongoing development of the weapon system for the U.S. Navy and MDA. Lockheed Martin pioneered the open-architecture software design of Aegis and each new program developed for Aegis becomes part of the Aegis Common Source Library, which allows the U.S. Navy and MDA to affordably and efficiently re-use and upgrade Aegis programing across a variety of defense platforms.
Maybe the Iranians are simply cashing in on the free passes that came with the Nuclear deal with compliments of the no drama Obama doctrine.WASHINGTON — The Pentagon says it briefly lost contact with two small Navy craft in the Persian Gulf on Tuesday but has received assurances from Iran that the crew and vessels will be returned safely and promptly.
Pentagon spokesman Peter Cook tells The Associated Press that the boats were moving between Kuwait and Bahrain when the US lost contact with them.
Cook says, "We have been in contact with Iran and have received assurances that the crew and the vessels will be returned promptly."
At the Surface Navy Association's (SNA) National Symposium currently held near Washington DC, Norwegian company Kongsberg is showcasing the Freedom and Independence variant Littoral Combat Ships (LCS), an Arleigh Burke class Destroyer (DDG 51) and a San Antonio class Landing Platform Dock (LPD 17) each fitted with eight Naval Strike Missiles (NSM).

"Kongsberg is showing what the distributed lethality concept could look like on a number of U.S. Navy vessels" Hans Kongelf, Vice President of Missile Systems at Kongsberg, told us during SNA 2016.
The distributed lethality concept was introduced (and is being advocated) by Vice Admiral Thomas Rowden, the Commander of the U.S. Navy's surface forces. It can be summarized by fitting more weapons on more vessels in order to "deceive the enemy, target the enemy, and destroy the enemy".
