“The U.S. Navy is exploring the viability of Subic Bay Hanjin Shipyard for use as a potential repair and maintenance facility,” Cmdr. Nate Christensen, the fleet deputy public affairs officer, said in an email Wednesday.

The shipyard’s owner, Hanjin Philippines, declared bankruptcy earlier this year owing $900 million to South Korean creditors. Since then, a pair of Chinese firms have expressed an interest in buying the facility sparking alarm in some quarters.

 

Sounds like a move to keep China from acquiring the shipyard.

Would counter rotating propellers provide the same benefits on ships as they do on aircraft? 

 

There's no need to worry about supersonic tip speeds on ships (with c0 = 1.5 km/s), but the rest of the aero/hydrodynamics is pretty similar

Philippines is looking to buy Brahmos.

“Talks are now ongoing for Philippine Army’s BraHmos missile acquisition project with India,” a senior military official bared, adding that BraHmos supersonic missiles are ideal for the Army’s land-based territorial defense operations.

Quote

“Once these BraHmos are finally procured and delivered, the Army will have the capability of defending the country from foreign aggressors and other territorial threats in the open seas,” a highly placed military source said.

Quote

“We, at the DND, fully support the recent amendment of Japan’s Self-Defense Force Act that would allow the Japanese government and its Ministry of Defense ‘the needed flexibilities’ for the Japanese military force ‘to play a greater role’ in maintaining peace and stability in the Asia-Pacific region by exporting quality defense equipment to foreign countries like the Philippines,” declared Defense Undersecretary Cardozo Luna at the inaugural launching of defense industry forum.

Why do the Queen Elizabeth class carriers carry so few aircraft relative to their size? 

I think that's because of the Highly Mechanised Weapon Handling System (HMWHS) on it, supposed to increase the number of sorties with lesser aircraft.

 

Plus probably there will be an increase in the number of aircraft.

 

I am just happy that they got like double the number of aircraft over their older carriers.

Too bad HMS Ocean was sold, a dedicated helicopter carrier is a must.

Got any links to the HMWHS? Is that what's taking up all the space?

HMWHS actually helps save space by having less crew, from some 160 people to 16 people with HMWHS.

 

The deck is also big because of the role these carriers will have, carrier strike + helicopter carrier.

 

It has a lot minor details for helicopter operations like that of two towers, five to ten helicopters at once ready for operation on deck, hangars for Chinooks without folding blades, lifts that can accommodate two Chinooks simultaneously with unfolded blades, space for the troops which will be transported by helicopter.

 

It also has four PTBs.

 

A beefed-up helicopter carrier with a taste for Sea Control+.
