The Pentagon is considering sending U.S. military aircraft and ships to assert freedom of navigation around rapidly growing Chinese-made artificial islands in the disputed South China Sea, a U.S. official said on Tuesday.

Defense Secretary Ash Carter requested options that include sending aircraft and ships within 12 nautical miles (22 km) of reefs that China has been building up in the Spratly island chain, the official said.

Such a move would directly challenge Chinese efforts to expand its influence in the maritime heart of Southeast Asia.

"We are considering how to demonstrate freedom of navigation in an area that is critical to world trade," the U.S. official said, speaking on condition of anonymity, adding that any options would need White House approval.

The US Navy (USN) on 11 May marked the retirement of the Sikorsky SH-60B Sea Hawk anti-submarine warfare (ASW) helicopter at Naval Air Station North Island in Coronado, California.
The SH-60B fleet is ending 30 years of service, with more than 3.6 million flight hours completed in support of operations and training during that time, the navy said in a statement.
The SH-60B first deployed with a Helicopter Anti-Submarine Squadron Light 43 detachment aboard guided-missile frigate USS Crommelin (FFG 37) in 1985, according to the navy. The last active-duty detachment returned from a seven-month deployment aboard guided-missile frigate USS Gary (FFG 51) on 17 April

The objective is to provide a dash of mobility, long-range scouting and fire support to units that mostly move on foot. An Airborne unit with ULCVs could airdrop into a remote location far from enemy forces, mount up, and race cross-country to seize an airfield for reinforcements to fly into. This kind of capability is crucial to the Army’s quest to become more

One of the leading contenders for the ULCV is Polaris, which last year

So what sets Polaris apart? “We came from the off-road business as opposed to the defense contractor business,” said Rich Haddad, general manager for Polaris Defense. Counting everything from

, he said, Polaris has sold over one million off-road vehicles over the last five years. That’s a scale unheard of in the defense business.

The commercial marketplace also operates at a radically different pace than does Pentagon acquisition. “We change models every year,” said Haddad. “Imagine the headache you’d have with that in a program of record; you’d just be buried by the change orders.” But the commercial experience does help speed up the military side, he said: DAGOR went from “a piece of paper with a concept [to] for vehicles being tested at the NTC [

Because of Polaris’s commercial experience, Haddad boasted, “we’ve been through this process more times than you can imagine, and we’ve had more successes and failures than all of our competitors combined.”

Not a very smart move . USN could of course navigate around those islands . It will be a show of strength, but in the end those ships would need to go, and Chinese would remain . Unfortunately, a bitter taste that US is again poking in Chinese backyard would remain - and a definite case for closer cooperation with Russia .

Interesting, I was under the impression that F-22 was equipped with AIM-9X for the last few years... strange that they're only integrating it now given how many legacy fighters have it, and given how much F-22 could have benefitted from a HOBS SRAAM for the last few years. Oh well, better late than never.

did you know there were four variants of the B-2 Spirit? Mods 3, 4, 7 and 10 I put in boldface below

will outfit the attack aircraft with next generation digital nuclear weapons called the B-61 Mod 12 with a tail kit — and speed up development of a nuclear cruise missile called the Long Range Stand-Off weapon or, LRSO, Eric Single, chief of the Global Strike division for Air Force acquisition, said in an interview with Military.com.

The LRSO will replace the Air Launched Cruise Missile, or ALCM, which right now is only carried by the
Please, Log in or Register to view URLs content!
, Single said.

“The 2016 president’s budget accelerates this program. We plan on a milestone in the middle of next year,” he added.

The B-61 Mod 12 is an ongoing modernization program which seeks to integrate the B-61 Mods 3, 4, 7 and 10 into a single variant with a guided tail kit. The B-61 Mod 12 is being engineered to rely on an inertial measurement unit for navigation, Single said.

“Four different variants will all be consolidated into a single variant. The tail kit will allow you to maintain a maneuvering tail and increase accuracy,” Single said.

The B-61 mod 12 is slated to enter production in 2017 and be finished by 2018, Single said.

“Software upgrades will help integrate the B-61 mod 12 into the B-2. This will upgrade storage management processors onto more capable integrated processors to bring more capacity to integrate a digital weapon like the B-61 Mod 12 or LRSO in the future,” Single explained.

In addition to the LRSO, B83 and B-61 Mod 12, the B-2 will also carry the B-61 Mod 11, a nuclear weapon designed with penetration capabilities, Single explained.

All the B-2’s nuclear weapons are engineered to function in a non-GPS environment.

“In that type of exchange, GPS would not be available to you,” said.

Alongside its nuclear arsenal, the B-2 carries a wide range of conventional weapons to include precision-guided 2,000-pound Joint Direct Attack Munitions, or JDAMs, 5,000-pound JDAMs, Joint Standoff Weapons, Joint Air-to-Surface Standoff Missiles and GBU 28 5,000-pound bunker buster weapons, among others.

The B-2 can also carry a 30,000-pound conventional bomb known as the Massive Ordnance Penetrator, Single added.

Communications Upgrades

The Air Force is also improving the communications technology designed into the B-2 to allow for greater connectivity in the event of a nuclear detonation, an event called an electro-magnetic pulse, or EMP, environment.

The service plans to enter production next year of what’s called a Common Very Low Frequency Receiver, a communications system which used uses Very Low/ Low Frequency, or VLF/LF, waveform.

This waveform is secure and beyond line of sight, however it will only transmit data and it is receive only, Single said. This means an air crew could receive targeting instructions from the president, but not be able to transmit information back in a two-way fashion, Single added.

Single explained that there are only two waveforms that would be survivable in this kind of scenario – one of them is EHF which would rely upon the Advanced Extremely High Frequency, or AEHF, satellite constellation and the other is VLF, he explained. Adding VLF waveform technology to the B-2 is expected to cost $160 million, Single said.

“VLF receivers will start going on planes in the next few years,” he added.

The new receiver will be added onto the B-2’s existing communications infrastructure which includes UHF-based satellite connectivity and something called the high-performance waveform, which comes from an on-board radio called the PRC 117.

“The B-2 has a large suite of communications systems on board that enable you to do line of sight and beyond line of sight voice and data. You have always had UHF connectivity which means you have always had a beyond line of sight data link,” Single said.

UHF connectivity, which is able to send and receive voice and data beyond line of sight, is recoverable in the event of a nuclear detonation but could be substantially degraded, he explained.

The Air Force is also exploring high-speed, high-frequency communications through the EHF waveform which would need the AEHF satellite constellation. Single said this could replace the existing UHF communication on Milstar satellites – in order to allow for survivable, two-way communication in the event of a nuclear attack.

“EHF has a higher data rate capability. It is also survivable and can transmit and receive. With the bandwidth you can get out of that you can send large volumes of data. The B-2 currently uses Milstar UHF which is not a survivable waveform,” Single added. “This would help us transition from everyday communications beyond line of sight to an EHF/AEHF satellite constellation.”

Northrop Grumman, the lead defense contractor on the B-2, owns a contract with a $9.9 billion ceiling to complete maintenance and modernization on the fleet of 20 stealth bombers. The fleet upgrade will also include new computer processors, avionics, radar warning receivers and communications gear.

The B-2 is also being engineered with a new flight management control processor designed to expand and modernize the on-board computers and enable the addition of new software.

The Air Force is currently fielding what’s called increment 1 of the improvements to the flight management control processors. The initial work on this will be completed by the end of next year, Air Force officials said.

“This provides more processing power for the avionics systems on the airplane. This improves the performance of the on-board computers by 1,000 times,” Single said.

The upgrades are also improving something called the Defensive Management System, or DMS, a radar warning receiver which helps detect and report threat information.

The $2.2 billion effort, which will replace some of the processors in the DMS system, is slated to be finishing up for delivery by 2021, Single said.

The

, Single explained.

The DMS technology is able to detect emissions coming from enemy air defenses and help display their location, allowing the air crew to avoid threatening air defenses and change course as needed.

The B-2, which costs about $2.2 billion per plane, can reach altitudes of 50,000-feet and carry 40,000-pounds of payload. First produced in 1989, the stealth bomber was engineered to deliver weapons behind enemy lines and evade Soviet air defenses.

The Air Force had expected to field a fleet of over 130 B-2s, but failures by Northrop Grumman and the Air Force to keep it under budget along with the end of the Cold War led the Pentagon to cut the fleet to 21.

No for B-2 for nuclear bombs B-61 the more small exist also B-83 much more powerful. For 2020 new B-61 Mod 12 less powerful but much more accurate with new guided tail kit also more small for be fitted in F-35 internal weapons bay.

B-2 Block 10, 20, 30 now. Initially Block 10 only nuclear capable after modified for use GPS bombs, conventionnal armament, get a special radar initially done for detect Soviet mobile targets mainly SS-24/25, PESA soon AESA radar.

I read the AMDR news
Raytheon Successfully Completes Critical Design Review for AMDR
The Raytheon-built Air and Missile Defense Radar (AMDR) has successfully completed its Navy critical design review (CDR) ahead of more hardware development efforts later this summer, company officials told USNI News this week.

According to the company, the AMDR — now designated AN/SPY-6(v) — passed or exceeded technical performance measures in tests allowing the company to proceed to the next phases of the design and building effort of the radar.

“We have achieved or exceeded all of those technical performance measures,” Tad Dickenson Raytheon’s program manager for AMDR told USNI News this week.
“The basic report card is that we have more than 20 technical performance measures which are anything from simple things — like size weight and power — to more complex things — like jammer suppression or single pulse sensitivity.”

The company had completed the

.

The AMDR will be the new active electronically scanned array (AESA)S-band radar onboard the Arleigh Burke Flight III guided missile destroyers (DDG-51). The first of the ships will start construction in Fiscal Year 2016 as part of a ten ship multi-year procurement deal the service inked in 2013.

Raytheon is also building a radar suite controller and the Navy will use the Northrop Grumman AN/SPQ-9B (nicknamed: spook 9 Bee) as the X-band radar for the Flight IIIs for now.

The radar promise to provide a 30-times boost in sensitivity over the current Lockheed Martin AV/SPY-1D radars found on current Burkes, the Navy has said.

Raytheon is currently working on an engineering development model ahead of a full radar delivery in May of 2017 to meet the construction schedule of the new Flight IIIs.
and there's this video in

which makes me wonder if
  • a smaller number than nine of Radar Modular Assemblies could be used? (of course the new Burkes will use a higher number than nine, as the video suggests, but I was thinking about smaller ships)
  • COUNTER BATTERY SEARCH & TRACK mean artillery shells can be followed? (I think I've read this option was dropped on the Zumwalts but I could be wrong ... am I?)

US Navy Declares Initial Operational Capability for New Rolling Airframe Missile RAM Block 2
ZUtgB2z.jpg

The U.S. Navy successfully achieved Initial Operational Capability (IOC) for the Block 2 Rolling Airframe Missile (RAM) aboard the amphibious transport dock ship USS Arlington (LPD 24) May 15. RAM is a highly successful, 39-year U.S. cooperative program with the German government that has yielded the U.S. taxpayer more than $800 million in cost avoidance and has delivered arguably one of the most capable anti-ship cruise missile defense systems in the world. The new RAM Block 2 missile is designed to counter advanced anti-ship cruise missile threats that U.S. and Allied Navies face today.
