..., you have to have a PLAN...

This was an intentional pun wasn't it...

No.

General Atomic contract for storage capacitors supplying High Power Microwave weapons.

"General Atomics Electromagnetic Systems (GA-EMS) announced today that it has been awarded a contract from the U.S. Navy through the Defense Ordnance Technology Consortium (DOTC) to develop advanced, high energy density capacitors for use in High Power Microwave (HPM) systems. GA-EMS is applying advanced technologies to create high energy density capacitors that will enable the deployment of HPM systems on smaller and more tactically relevant Navy platforms."

I wonder why the turret is mounted so far forward on the Chinese ship?   It would surely be unstable in that position.

Safer sabot/armature separation?

If it was amidships you'd fire it with the barrel directed amidships.   Placing the turret that far forward means that it would be subject to excessive pitch when waves hit the ship.   If this was a trials ship, it would be to prove that the weapon could be deployed on a ship and I suspect most firing would occur when the ship was stationary.

Have we actually seen any of the double-digit MJ EMRGs at any appreciable angle of elevation?

That raises more questions than it answers.  Why don't the larger copper discs go to the end of the barrel?  Are they for cooling?  Does it take a big jolt to get the round moving and maybe less to keep accelerating?  Coil-gun first then railgun (maybe to reduce a giant arcing hotspot as the round goes from resting to moving)?  ???

Hi,

I think the massive chunk of metal is the breech, containing the high power connections. A railgun is literally just two rails with a conducting projectile across them (you can make one yourself with some copper wire and a power supply). They are contained inside a strong casing of some sort - it appears to be a composite fibre-wound structure in this case.

Thank you for posting.

Radar verses open rotors & tiltrotors equals expensive crash site.. Dumbafied.

Just like quadrotor per Marine squad equals squad under mortar fire. Add new penchant for automatic 82mm mortars. Dumbafied

Could we get that in English please?  You can't possibly be baffled that world militaries use helicopters and drones so you must be trying to say something else. What?

If one service has made sufficient progress to use laser weapons in its arsenal in the next few years, it's the U.S. Navy, according to the former director of the Missile Defense Agency.

"The Navy right now is the most forward-leaning because they're the only service that has actually fielded an operational prototype weapon, the Laser Weapon System that they put on the USS Ponce," said Trey Obering, an executive vice president at consulting firm Booz Allen Hamilton who leads the directed energy innovation team.

Military.com spoke with Obering, a former Air Force lieutenant general, fighter pilot and NASA space shuttle engineer, in the midst of this week's Directed Energy Summit hosted by Booz Allen Hamilton and the Center for Strategic and Budgetary Assessments.

Sort of.  Started life as an M113 tube for the M107 175mm gun but they smoothbored it and extended it by 10 feet or so.

Edit: the attachment is a review of the HARP program from the Army Ballistics Research Laboratory that talks about the smaller demonstrators, not just the famous 16-inch tube.  Photos are illegible but the text is interesting.

Thank you for posting , Sounds like it should be the start of the Army Strategic Fires Artillery Cannon not just a commercial venture.

Solar powered Hydrogen piston sounds unbeatable.

USAF prepares for rapid demo of high-energy laser weapon

15 May, 2018

The US Air Force has started preparing to rapidly stage a demonstration of a highly mature laser weapon system (LWS) for an unspecified “airborne vehicle”, with the potential for a follow-on production programme.

The plans for the near-term demonstration of a “High Energy Laser (HEL) Flexible Prototype” programme are revealed in an 11 May notice to potential suppliers from the Air Force Life Cycle Management Center (AFLCMC).

The notice outlines a plan to pay a supplier to deliver a HEL prototype and perform a system level ground verification test of an LWS within 12 months of contract award.

“The success of meeting this schedule milestone is the primary factor for continued work toward the flying prototype and the possibility of future LWS production,” the AFLCMC says.

The new request for information comes about a year after Eglin AFB published an RFI for “Airborne Tactical Laser Technology”, which solicited information about various subsystems that would be needed for an HEL.

“Those responses have been reviewed,” the AFLCMC states in the acquisition notice.

Nearly a decade ago, the Air Force Research Laboratory wrapped testing of a 100kW-class chemical oxygen iodine laser on a Lockheed Martin C-130 after an Air Force Scientific Advisory Board report determined the weapon had “no tactical utility”.

But interest in such a weapon never waned — especially for Air Force Special Operations Command. Since the late-1990s, the organisation has lobbied for funding to develop a laser weapon for its C-130 gunships.

Following the demise of the Advanced Tactical Laser programme in 2009, AFSOC’s interested shifted to solid-state laser technology.

Last month, AFSOC commander Lt Gen Marshall Webb complained in Senate testimony that a programme to install a 60kW-class laser weapon on an AC-130J Ghostrider gunship by 2022 is moving forward, but is $58 million short of full funding levels.

Meanwhile, the AFRL also has funded a self-protect high-energy laser demonstrator (SHiELD) programme for aircraft.
