US to use drone submarine hunters

Daily Mail:

The Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel (ACTUV) is developing an unmanned vessel optimized to robustly track quiet diesel electric submarines.The US Navy's 'ghost hunter' hits the water: Robo-boats set to track down silent enemy submarines for months at a time


The ACTUV will be able to operate for several months at a time scouring the seas and coastal areas for silent, diesel powered enemy submarines, and is being tested in Mississippi.
This appears to be a more cost effective than using more expensive hunter killer subs to chase the new subs.  The drone will have sophisticated electronics that will help it track the new ultra quite subs.

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.

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...

Is the F-35 obsolete?

Headline USA: Pentagon Fires Back after Musk Calls Its Most Expensive Project ‘Obsolete’ 'Yeah, as I'm sure you can appreciate, Mr. Musk is, currently, a private citizen, I'm not going to make any comments about what a private citizen may have to say about the F-35....'   ... ... Drones appear to be replacing jets for many operations.  The Russia-Ukraine war is an example of that.  Drones are often hard to detect and can be used for intelligence operations as well as for attacking enemy targets.  It would not surprise me to see drones engaging other drones in combat.  They also cost much less than manned fighters.
