US rail gun tech to pack more power in a smaller package

Sea Power Magazine:
General Atomics Electromagnetic Systems (GA-EMS) has developed a High Energy Pulsed Power Container (HEPPC) that provides twice the energy density than existing railgun pulsed power solutions, the company announced in a March 9 release.

The HEPPC can reduce the number of pulsed power containers required to launch projectiles or hybrid missiles from a railgun weapon system, providing greater flexibility for future Navy and Army railgun applications.

“For the past decade, GA-EMS has provided pulsed power in support of the Navy’s railgun program,” stated Nick Bucci, vice president Missile Defense and Space Systems at GA-EMS. “Our next generation HEPPC breaks our own energy density record and exceeds the capabilities of other available railgun pulsed power container solutions. What we have packed into a 10-foot standard shipping container is equivalent to what is currently available in a 20-foot shipping container, doubling the energy density to provide greater flexibility for ship and land-based installations and maneuverability for mobile applications.”

GA-EMS internally funded the development of the HEPPC in support of a Multi-mission Medium Range Railgun Weapons System, which integrates pulsed power, launcher, hybrid missile and fire-control technologies. Each HEPPC includes high-energy pulsed power modules with an energy content of more than 415 kilojoules per module. Each module utilizes GA-EMS’ world-record-breaking high-energy density capacitors.

The rail gun could be the future for artillery on both land and sea and possibly a space based weapon if they can continue to shrink the size of the weapon.  It can give the Navy greater standoff capability.  It will be interesting to see this weapon used from a ship.

Should Republicans go ahead and add Supreme Court Justices to head off Democrats

Washington Post: Some Democrats eye adding more justices to the Supreme Court to change its ideological bent The once-remote idea has gained the attention of liberals angered by the GOP push to remake the federal courts. Probably the easy way to defeat this court-packing scheme is for Trump to propose doing the same thing now.  It would lead to Democrat denunciations and claims that it would be wrong, thereby blowing up any attempt by them in the unfortunate event of Democrats winning a presidential election.

29 % of companies say they are unlikely to keep insurance after Obamacare

Conn Carroll: A new survey of 368 midsize to large companies found that 29% of them are considering terminating their active employee health care plans when Obamacare is full implemented in 2014. Only 71% of employers surveyed said they did not expect to drop their health coverage, while 20% said they did not know and 9% said they were planning to exit. The latest survey, conducted by Towers Watson, echoes an ealier survey by McKinsey & Co. finding that 30% of private-sector employers were planning to drop their employee health insurance coverage by 2014. When the Congressional Budget Office crunched Obamacare's spending numbers, they estimated that only 7% of employees currently covered by employer-sponsored plans would lose their plans. ... This means the cost of the health care fiasco will be hundreds of billions more than estimated by the CBO and Congressional Democrat. It is also clear that Obama's pledge that you could keep your health care plan if you wanted t

Bin Laden's concern about Zarqawi's remains

James Robbins: ... Bin Laden suggests that President Bush should allow Zarqawi’s body to be returned to his family in Jordan, but this is a matter that is up to the Jordanian government, which so far has not shown much interest in facilitating a homecoming. Bin Laden mocks King Abdullah II, calling him a Coalition minion, and asking “w hat scares you about Abu Musab after he’s dead? You know that his funeral, if allowed to happen, would be a huge funeral showing the extent of sympathy with the mujahedin.” A large crowd would definitely turn out, though most people would be on hand to demonstrate their anger and disgust. Last November’s hotel bombings in Amman , masterminded by Zarqawi, are still fresh in people’s memory, and mentioning them to Jordanians has the same visceral impact as memory of the 9/11 attacks does here. Jordan has adopted a zero-tolerance policy towards those who choose to mourn the country’s least favorite son, and four opposition members of parliament who paid con
