The American aircraft carrier USS John Stennis has passed the Strait of Hormuz and entered the Persian Gulf after patrolling the Arabian Sea together with a guided missile cruiser USS Mobile Bay, the US Navy reports. The warship is currently docked in Saudi Arabia’s port of Jebel Ali.



On December 28, the USS John Stennis is going to take part in 6-day naval drills in the Strait of Hormuz and the nearby Gulf of Oman.

Iran’s Navy has announced it will stage live-fire exercises in the same region to practise sealing off the strait, which accounts for over 20% of the world's oil shipments.

Meanwhile, the amphibious assault ship USS Peleliu has entered the Oman’s port of Salalah on the Arabian Sea.

Navy issues urgent order to equip MQ-8 helicopter UAV with maritime surveillance radar



December 30, 2012



Posted by John Keller

PATUXENT RIVER NAS, Md., 30 Dec. 2012. U.S. Navy officials have issued an urgent order to equip the service's MQ-8B Fire Scout unmanned helicopter with the Telephonics Corp. RDR-1700 maritime-surveillance radar system.

The Northrop Grumman Corp. MQ-8 Fire Scout is a rotorcraft unmanned aerial vehicle (UAV) deployed on Navy frigates, littoral combat ships, and other surface combatants for reconnaissance, situational awareness, and precision targeting.

Officials of the Naval Air Systems Command at Patuxent River Naval Air Station, Md., awarded the Northrop Grumman Aerospace Systems segment in San Diego a $33.3 million contract earlier this month to install the Telephonics RDR-1700 maritime-surveillance radar on nine Fire Scout UAVs.

Navy officials say they want the quick-turnaround contract completed within one year. The hurry-up order comes from the chief of naval operations under terms of an urgent operational needs statement (UONS), as part of a rapid-deployment capability (RDC) radar program for the MQ-8B Fire Scout.

The radar system for the Fire Scout consists of the Telephonics RDR-1700 radar system, modified MQ-8B radome, and interfaces into the helicopter UAV and its control station.

Northrop Grumman is the original manufacturer of the Fire Scout, and is the only source able to integrate a complex radar payload into the existing Fire Scout unmanned helicopter within the required time, Navy officials say.

Northrop Grumman designed the key interfaces to integrate the radar on the Fire Scout, which will require modifications to the Fire Scout payload interface unit software. Northrop Grumman owns the data rights to the Fire Scout's data link control processor software, which must be modified as part of this project, officials say.

The Fire Scout is a version of the Schweizer 333 turbine-powered manned helicopter from Schweizer Aircraft Corp. in Horseheads, N.Y., which is a Sikorsky Aircraft company.

The Telephonics RDR-1700 search, surveillance, and weather-avoidance radar system is for airborne search and surveillance while secondary roles include terrain mapping, weather avoidance, and beacon navigation. Telephonics Corp. is based in Farmingdale, N.Y.

The RDR-1700 is a lightweight, X-band digital color radar system that functions as a 360-degree belly-mount or 120-degree nose-mount scanning sensor. The system has three line-replaceable units -- the antenna/pedestal, receiver-transmitter, and interface unit.

The RDR-1700 offers standard display modes including aircraft heading reference, north-oriented and ground reference, and has target-marker capability that enables the operator to determine range and bearing of a target from the UAV and between targets.

System capabilities include: long-range navigation position update, and target position transmission. The 20 target track-while-scan processor provides location latitude and longitude, target heading, and velocity.

Argon ST has been supporting the Nixie program for the Naval Sea Systems Command since 2002, and has received multiple follow-on awards with options. The order announced today is the first option exercised under the current contract. Production of the new systems will begin in February, primarily at Argon ST's facilities in Smithfield, Pa.

Argon ST is the sole contractor for the design, development and manufacturing of the AN/SQL-25C system, which is protecting more than 400 vessels in navies from more than 20 countries around the world. Nixie is one of Boeing's C4ISR capabilities that support customers' enduring need for situational awareness.

General Dynamics Awarded $4.6 Billion for Submarine Programs

(Source: General Dynamics; issued Jan. 4, 2013)



In addition to working on the Ohio Replacement Program SSBN, GD said Jan. 4 it will also build two new Virginia-class SSNs (above) and prepare for the next three. (USN photo)GROTON, Conn. --- General Dynamics Electric Boat was recently awarded three U.S. Navy contracts totaling $4.6 billion to design and develop the next-generation strategic deterrent submarine, and to continue construction and purchasing of materials for Virginia-class attack submarines. Electric Boat is a wholly owned subsidiary of General Dynamics.

Under a five-year, $1.85 billion Ohio Replacement Program contract, Electric Boat will perform research and development work for this new class of ballistic-missile submarine, which is scheduled for a 2021 construction start. Additionally, Electric Boat will continue development of the joint U.S. Navy / Royal Navy Common Missile Compartment for Ohio Replacement submarines and the UK Successor-class ballistic-missile submarine. The potential value of this contract is $1.995 billion.

Electric Boat also received a $2.5 billion award to build two Virginia-class submarines - South Dakota (SSN-790) and Delaware (SSN-791) - the 17th and 18th ships of the class. Construction of Virginia-class submarines is shared between Electric Boat, the prime contractor, and its teammate, Newport News Shipbuilding.

Under the third award, Electric Boat will receive $308 million to purchase long lead-time materials for the as-yet unnamed Virginia-class submarines SSN-792, SSN-793 and SSN-794.

"These awards provide the stability to the submarine industrial base that will allow us to achieve even greater cost reduction through improved efficiencies in support of the Navy's submarine force-level requirements," said Electric Boat President Kevin J. Poitras.

"We appreciate the support of the Connecticut and Rhode Island congressional delegations, which are instrumental in educating their colleagues and others about the vital national-security need for a strong submarine force, helping to pave the way for these contracts," Poitras said.

Attack sub collides with ship in Persian Gulf


An attack submarine collided with a small, civilian vessel in the Persian Gulf on Thursday, damaging one of the sub’s periscopes but not harming anyone on either vessel, 5th Fleet said Thursday.

The attack sub Jacksonville was at periscope depth at 5 a.m. when it collided with the unidentified vessel.

“Damage appears to be limited to one of Jacksonville’s two periscopes,” 5th Fleet said in a statement Thursday. “The reactor remains in a safe condition, there was no damage to the propulsion plant systems and there is no concern regarding watertight integrity.”

A Navy official familiar with the initial reports said the top portion of the periscope had been sheered off while the lower part was left bent, a condition first reported by The Associated Press.

The other vessel continued on its course and speed and did not respond to hailing calls, officials said. A subsequent P-3 Orion search didn’t locate any vessels in distress and 5th Fleet spokeswoman Lt. Marissa Myatt said the Navy had not been contacted by the vessel, which appears to be a small fishing vessel from reports.

Jacksonville is transiting the Persian Gulf and will head back into port to get the damages assessed, Myatt said. It is the sixth Navy vessel to sustain a collision at sea since May.

5th Fleet said the incident is under investigation. Investigators are attempting to identify the other vessel using the ship tracking system AIS.

Jacksonville left its home port of Pearl Harbor, Hawaii, on Nov. 5 for a six-month deployment. For more than half of the crew, this would be their first cruise, the commanding officer said at the time.

“They are anxious to go out there and do what submarines do at the pointy end of the spear,” Cmdr. Nate Sukols said in a Nov. 6 Navy news release.

Most crew leaves US Navy ship stuck in Philippines
MANILA, Philippines (AP) -- Most of the sailors on a U.S. Navy minesweeper that struck a coral reef in the Philippines left the ship Friday for safety reasons after initial efforts to free the vessel failed, the Navy said.

The ship ran aground Thursday while in transit through the Tubbataha National Marine Park, a coral sanctuary in the Sulu Sea, 640 kilometers (400 miles) southwest of Manila. There were no injuries or oil leaks, and Philippine authorities were trying to evaluate damage to the protected coral reef, designated by UNESCO as a World Heritage Site.

The U.S. Navy's 7th Fleet said 72 of the 79 crew of the USS Guardian were transferred to a military support vessel by small boat. A small team of personnel will remain aboard and attempt to free the ship with minimal environmental impact, the statement said. The remaining seven sailors, including the commanding and the executive officer, will also be transferred if conditions become unsafe.

Philippine officials said the weather was choppy Friday with strong winds and rough seas.

Next generation US submarines will refuel once every 50 years and have quieter electric drive

missile Ohio Replacement (OR) program will be built around a drive that will not need to be refueled for the 50-year life of the boats and cuts out potentially noisy direct mechanical connection to the drive train. In other words, the Navy’s next-gen subs could be almost silent, and keep running for a half-century straight. The Navy is developing an innovation that attempts to give OR boomers the quietest nuclear engine yet by going to an electric drive.

The Navy wants to use the power from the reactor to create an elaborate electrical grid inside of the submarine. The reactor power would feed the grid and in turn the electric motors that would drive the boats. Eliminating the mechanical connection would mean less noise under water. The set up would also free up power previously devoted to driving the ship. Currently anywhere from 75 to 80 percent of the power from a nuclear submarine is devoted to driving the ship through the water. Extra power could be routed to other systems like sonars and potentially unmanned underwater vehicles.



Current submarines have a direct mechanical connection to the props that drive the boat. Steam turbines driven by the nuclear power plant go through a series of mechanical gears that translate the high torque power from the nuclear plant into lower torque energy needed to propel the ship. All of those mechanical connections can generate noise, the bane of the submariner.

This will be the second try for the Navy to use electric drive subs. The service experimented with the technology in the 1960s and 1970s but found the boats equipped with the drives to be underpowered and maintenance heavy.

Currently the US navy fields 14 Ohio-class boomers packing 24 Trident II D5 intercontinental ballistic missiles. (The first four Ohios were converted to carry missiles with conventional warheads).

“There are still going to be midlife upgrades but the refueling portion is effectively eliminated which allows us to reduce from today’s 14 Ohios to reduce down to 12 Ohio Replacements,” Stackley said.

The original Ohio-class builder General Dynamics Electric Boat hasn’t built a boomer in more than 20 years and the durability of the drive and the boats to last until 2080 is a tall order.

Added to the pressure is a Pentagon imposed cost cap that reduce the cost of the boat from about $7 to 8 billion down to $4.9 billion. But the Navy will have little margin for error if they want to keep the price tag that low.

The Navy has already delayed work two years as part of its 2013 budget. Currently the first OR boat is scheduled to begin construction in 2021 for a decade-long construction and development process. The super-silent boat is scheduled to make its first patrol in 2031

Navy seeks to replace Air Surveillance Radar on ships

The Naval Air Systems Command (NAVAIR) is seeking a replacement for the AN/SPN-43C Air Surveillance Radar (ASR) in order to resolve ongoing obsolescence issues and radar signal processing deficiencies, according to contract documents released on Friday through the Federal Business Opportunities website.

The AN/SPN-43C ASR is a radar system used for Carrier Air Traffic Control with 50-mile search capability up to an altitude of 30,000 feet. It ensures safe and expeditious shipboard approach, departure, and marshal control to support fleet operations for aircraft carrier and amphibious assault ships.

NAVAIR tentatively plans to conduct a full and open competition for the AN/SPN-43C ASR Replacement in fiscal year (FY) 2014, or early FY 2015, in anticipation of an engineering and manufacturing development contract award by June 30, 2015.

In order to permit NAVAIR to conduct market research and assess industry interest in this requirement, an Industry Day for the AN/SPN-43C ASR Replacement will be held Feb. 26-28 at the Naval Air Warfare Center, Aircraft Division in St. Inigoes, Md. (Webster Field).

The market research gathered during the Industry Day will be utilized by the government to identify the air traffic control capabilities that presently exist in the marketplace.

A general session open to all interested parties will be conducted during the morning of Feb. 26. This general session will address the current status of the AN/SPN-43C ASR Replacement effort, discuss known operational environments for the replacement, discuss a notional schedule for conducting the full and open competition for the radar replacement, and receive vendor feedback.

In addition, potential prime contractors for the AN/SPN-43C ASR Replacement will be afforded the opportunity for one-on-one discussions with the government. These one-on-one sessions will be held during the afternoon of Feb. 26 and all day Feb. 27 and 28.

TOPGUN Training at NAS Pensacola





NAS PENSACOLA, Florida --Fifteen aircraft, 140 military and civilian personnel, TOPGUN is at NAS Pensacola for two weeks.

"To give the students a little bit better and realistic training. Fighting at sea level essentially," says commander Kevin McLaughlin.

They are the top fighter pilots in the world. Billed as "the best of the best", but some of the F18's and F16's used to train these topguns are as old as the movie that made them famous.

"We are flying mostly F18's Echo and Foxtrots Super-hornets. The F16s are used primarily as aggressors, adversary aircraft. So these aren't Navy deploying aircraft. They are used for the TOPGUN course."

Eventually these jets will be replaced with F35's but cost over-runs and performance problems have delayed training but hasn't stopped it. "We're already beginning to develop tactics for the F35. A number of instructors on staff are working with engineers and flying in the simulators to develop what's coming down the pipe," says McLaughlin.

This isn't the first time TOPGUN has been at NAS Pensacola, in fact they were here last fall but just having them here is kind of an insurance policy according to NAS spokesman Harry White. "This really gives us an opportunity to demonstrate our value not only to the U.S. Navy but to the Department of Defense."

The sound of jets dogfighting over Pensacola will last for another week or so, "There will always be a need for it," a sound that provides a sense of security for NAS Pensacola and the world.

Raytheon, US Navy demonstrate new dual targeting capability for JSOW C-1


Weapon hits two stationary land targets during integrated test phase


CHINA LAKE, Calif., Jan. 22, 2013 /PRNewswire/ -- The U.S. Navy successfully demonstrated the dual targeting capability of Raytheon Company's (NYSE: RTN) Joint Standoff Weapon (JSOW) C-1. Two recent tests during the program's integrated test phase prove the weapon can engage challenging stationary targets. Previous testing in the integrated test phase demonstrated JSOW C-1's capability against moving maritime targets.

The first stationary land target test was designed to assess JSOW's capability against operationally realistic infrared and radio frequency countermeasures. An F/A-18F Super Hornet aircraft launched a JSOW C-1 from approximately 29,000 feet and 17.5 nautical miles from the target. The weapon flew a preplanned route at 0.83 mach airspeed, employed 3-D waypoints, and successfully impacted a cement wall on a simulated bunker.

The second stationary land target test was designed to demonstrate JSOW's performance at night against an operationally representative bunker target. An F/A-18F Super Hornet launched the JSOW C-1 from approximately 25,000 feet. The JSOW C-1 flew the preplanned route at 0.81 mach airspeed and successfully impacted the buried bunker. Both tests occurred at the U.S. Naval Air Weapons Station in China Lake, Calif.

"These tests demonstrate that JSOW C-1 provides the U.S. and allied warfighters with a new dual capability to engage both stationary land targets and moving ships at range," said Celeste Mohr, JSOW program director for Raytheon Missile Systems. "These tests help clear the way for the important operational test phase of the program scheduled to begin early next year."

The JSOW C-1 is designed to provide fleet forces with the capability and flexibility to engage moving maritime targets, while retaining its robust capability against stationary land targets. The weapon is a modification to the existing JSOW C, which adds a weapon datalink radio and modified seeker software to increase capability for the anti-surface warfare mission.
