US developing a cannon with a range in excess of 1,000 miles

 Popular Mechanics:

The U.S. Army is working on a new, long-range cannon it claims can reach out and strike targets at up to 1,150 miles. If the technology works, the Strategic Long Range Cannon (SLRC) promises the ability to fire 50 times farther than existing guns. But the new gun also has the potential to bring back a dormant class of big-gun warships once thought gone for good: the mighty battleship.


Earlier this year, Popular Mechanics published leaked photos showing the capabilities of the SLRC. With an effective range of 1,000 nautical miles—at 1,150 miles, that's about 1,130 miles farther than existing guns—the SLRC could be a truly revolutionary breakthrough in artillery warfare.

The Army hasn’t explained how it will reach such a mind-bending range, but it seems confident the gun will work as planned. A committee formed by the National Academies of Sciences, Engineering, and Medicine is currently taking a look at the technology to determine its feasibility, and the service plans to test a prototype in 2023. The Army envisions the SLRC as a towed gun pulled by a heavy truck, using its range to blast a hole in enemy air and sea defenses big enough for U.S. forces to squeeze through.

A single ship could carry the entire four-gun battery the Army envisioned deploying SLRC abroad, plus shells to keep the guns firing. A warship could relocate the guns at sea without asking anyone for permission, and would be more difficult for enemy forces to target. It would also have greater flexibility, deploying into areas where local allies might not be willing to host big guns.

...

World War II battleships had a maximum range of under 24 miles so this cannon would give a ship a range comparable to that of an aircraft carrier. How the ship would be stable enough to be an accurate base for firing that distance is not clear.

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
