pacific Sentinel said:
SAN DIEGO - USS Green Bay (LPD 20) departed San Diego Jan. 26 for Sasebo, Japan, where the San Antonio-class amphibious transport dock ship will join U.S. 7th Fleet's Forward Deployed Naval Forces.

Green Bay is replacing the decommissioned Austin-class amphibious transport dock ship USS Denver (LPD 9), previously forward-deployed to Sasebo, and will enhance amphibious presence in 7th Fleet as part of the U.S. Navy's long-range plan to send the most advanced and capable units to the Asia-Pacific region.

"The crew has worked hard to get Green Bay ready," said Commanding Officer Capt. Kristy McCallum. "By my count, we completed a total of 23 training, certification and maintenance cycles in six months. As we've trained, we have prepared ourselves to be ready for a dynamic security environment and diverse missions."

In addition to the many capabilities inherent to amphibious transport dock ships, Green Bay will bring a host of new technological advancements and warfighting capabilities to 7th Fleet.
Green Bay is equipped with an advanced command and control suite, increased airlift capacity, substantial increases in vehicle and cargo carrying capability and advanced ship survivability features. The ship supports the rapid transfer of personnel and equipment via landing craft, helicopters, and MV-22 Osprey tilt-rotor aircraft, making this ship a critical element for amphibious ready groups and expeditionary strike groups.

In 7th Fleet, Green Bay will become part of the USS Bonhomme Richard (LHD 6) Amphibious Ready Group (ARG). The ARG integrates regularly with the 31st Marine Expeditionary Unit to ensure the services are trained and ready to operate together to provide the most efficient amphibious fighting force in the Asia-Pacific region.

Green Bay was commissioned in January 2009, embarked on its maiden deployment February 2011 and completed a second deployment in 2013. The ship has since undergone a year-long maintenance availability in British Aerospace Engineering (BAE) systems shipyard and a dry dock period at the National Steel and Shipbuilding Company (NASSCO) in preparation for forward deployment to Japan.

Four points Ahho
1) the Exacto round is only in testing and even if it were to go production its not a alternative as its likely to be limited to larger calibers
2) any sighting system requires zero. Exacto still requires aiming of the rifle and sighting of the target, so Ahho no matter if you use a conventional rifle or a Trackingpoint system a Zero is still a need. And in the case of Trackingpoint rifles they are both factory zero-ed as well as designed specifically to self zero. They do this by using a laser reference hard mounted to the barrel. When a user "tags" the target the sight module fires a IR laser at the reflector reference zeroing the weapon and sight.

3) the cost of a Exacto round will be significantly higher than that of any conventional match or sniper rifle round. A case of such round would like be more expensive than a single trackingpoint rifle. But for 90% of combat shooting the self adjustment would be unnecessary or impractical. Where a Trackingpoint system would be more then adequate for accuracy at shorter ranges.
4) given the way Exacto rounds operate and Tracking point weapons are designed I personally don't think it should be one or the other but both together as a they can be a mutually beneficial relationship. The spotter designated the target at extended range of a shot over a mile. The sniper loads a Exacto round and tags the target the tracking point system makes adjustments and gives the point of aim. The sniper lines up the weapon which will at such ranges be at the very max elevation. Sniper pulls the trigger the tracking point system's electronic trigger supplies the hold until the weapon is in optimal position. The Exacto round is fired. It follows its ballistic trajectory until it sees the laser designated target. The laser being painted by the spotter who's spotting scope sees data from the snipers scope and can tag for it to. The spotters lasing allows the Exacto to make course adjustments allowing first hit kills.

For Point 1 and 2, that I definitely understand. What I am trying to say is that the concept of EXACTO allows sniper to go from place to place without worrying to re-zero the rifle.

On point 4, if this concept became real, this will be very useful for assassinations and hitting high value targets

various designs considered ...
“We deleted the composite mast and deleted the aft house. We took the Marines down to 500 and took half of the medical space away. We took four engines down to two,” said Mike Duthu, director of new Navy programs, Huntington Ingalls. “We deleted a generator, deleted the electrical load topside and we also made some of the systems simpler.”

AC130 retirement and design changes in the works.
To summarize, The USAF is moving to slow the retirement of it's AC130U, as realistically the potent 105mm Howitzer mounted in the bird is more cost effective then the smart bombs and 30mm currently in the interim AC130W Stinger II and production AC130J Ghostrider. The Air Force will retain the W ( little more than Harvest Hawk) and now modify production AC130J with the M102 105mm Howitzer standard,
to understand the logic and it's very good logic. a 105mm shell cost $400.00 a missile shot? a low cost missile 312 fold. AC130 can also carry a lot more 105mm shells then missiles and the have a smaller warhead then a SDB well still being precision.

Not to mention putting the fear of God onto the enemy. Sometimes all you need to do is make an appearance and people dissapear w/o needing to fire a single shot. Psychological warfare is seldom taken into account when considering these things but they play such an important role IMHO.

Just like you only need to hear the GAU-8 .. you hear the props or the

You only need to hear these sounds ONCE and it stays in your memory forever.
These gunships are excellent for non-symetrical warfare. F-35 and other 5th gen fighters are all good and bad but when you fight a low tech enemy you need 'low' tech equipment with tons of firepower. Apaches, AC130s and A10 bring real lasting pain. An AC130 raining thousands of 25mm, 76mm ,105mm down on a convoy or a structure etc puts the fear of God that simply cannot be match by dropping a couple JDAMs from altitude or a cruise missile hit from 500 miles away.

Kwai, Armament for AC130 Variants has varied but never included a 76mm gun.
First generation had 7.62x51mm miniguns and 20mm Vulcan cannons
then came 762 miniguns, 20mm Vulcan cannons and 40mm L60 Bofors
then AC130E and AC130H with 20mm vulcans 40mm Bofors and 105mm howitzer.
Ac130U upgraded to 25mm Equalizers 40mm Bofors, and a M102 105mm Howitzer

The AC130W is based on the USMC harvest Hawk which is a rear ramp mounted weapons launcher and a 30mm Bushmaster III with the addition of wing mounted weapons based on MC130W's
AC130J will be identical to AC130W except based on C130J and now including a M102.
the 40mm L60 Bofors cannon was a WW2 anti aircraft gun widely used by naval and Armies world wide. by late war Jets started to appear and the L70 was created with a faster rate of fire. that gun is the standard for swedish CV90. by the 60's the 40mm Bofors started being phased out by the L70 Mark 1 a 57mm gun a derivative of which the Mk 110 57 mm gun is in US service and has been fitted to LCS classes. 76mm is another naval gun but the size and weight would be prohibitive on a C130

USAF chooses 747-8 as next Air Force One

as the next generation of aircraft specially outfitted to carry the US president.

Air Force Secretary Deborah Lee James says “the

is the only aircraft manufactured in the United States that, when fully missionised, meets the necessary capabilities established to execute the presidential support mission, while reflecting the office of the president of the United States of America consistent with the national public interest.”

The Air Force intends to purchase up to three 747-8s, but has not yet formalised a contract with Boeing. The decision was made through a "determinations and findings" document.

When Air Force officials launched the presidential aircraft recapitalisation programme more than a year ago, they considered holding a competition to select a contractor to transform the civilian airliner's interior and systems into Air Force One.

The service now intends to award Boeing a sole-source contract to modify the aircraft with subsystems that "must seamlessly interface with each other and the 747-8 commercial aircraft systems in order to meet the Presidential ‘no fail’ mission.”

Air force documents say Boeing was selected for the systems integration work because other companies “would face significant challenges” securing Federal Aviation Administration approval of the completed airraft.

The new 747-8s will replace the current 747-200 aircraft, designated by the air force as the VC-25, that serve as Air Force One when the president is aboard.

Boeing will manage, design, test, certify and provide pre-operational training for up to three aircraft.

The announcement is a huge boost for Boeing’s commercial production line for the 747-8, which is exclusively powered by General Electric GEnx-2B engine.

At current production rates, Boeing will deliver the last 747-8 now under contract in early 2017. There typically is an 18-month lead time to place a new order without a work stoppage at the final assembly stage. Unless Boeing receives further orders for the passenger or freighter versions of the 747-8,the air force would need to finalise a contract by the end of 2015 to avoid a costly break in production.

Boeing delivered both VC-25s as the last two 747-200s off the production line in 1990.

The Air Force already knew it would need a four-engine, wide-body aircraft to meet the needs of the Air Force One mission, which carries the president on long-haul journeys and serves as a command post during emergencies. The Air Force in 2007 first approached

and Lockheed about the C-5. Airbus subsequently declined to offer the A380 for the competition, saying it would be impractical to set up final assembly in the USA.

747-8 was more or less the only choice. Airbus Early on said they would not offer the A380 as it would not make a profit to build a handful of those Flying Cruise Liners in the US just for the USAF. so it was Boeing vs.... No one. Lockheed long ago left the Commercial Airliner business and MD merged with Boeing. the options were 747-8 and 787 and in terms of square footage 747-8 for the win. if all goes well the next president will be the first to get a Ride in these. specs wise these birds will likely be major upgrades over the current VC25's that means EMP hardened with advanced communications including video conferencing and satellite TV. What will it look like?
Well I happen to have a link to Greenpoint Technologies who do Boeing contracts for this class.

Naval Today said:
US Navy’s amphibious assault ship USS Bonhomme Richard (LHD 6) recently docked in White Beach, Okinawa, to embark the 31st Marine Expeditionary Unit (31st MEU).

During the vessel’s stay at the dock, the Landing Craft Air Cushion (LCAC) 9, assigned to Naval Beach Unit (NBU) 7, departs the pier towards the amphibious assault ship and maneuvered into its well deck.

Bonhomme Richard, the lead ship in the Bonhomme Richard amphibious group, is currently deployed in the U.S. 7th Fleet Area of Responsibility.


In addition to a full compliment of assault helicopters and a wing of AV-8B HArriers, the Marines on this vessel will also get to shore with US LCACs.
