.

Since then, the Navy has ordered enough of the watches for all Hornet and Growler squadrons, Naval Air Forces spokeswoman Cmdr. Jeannie Groeneveld told Military.com Thursday.

"We aim to have 100 percent of our fleet squadrons equipped with the watches by August," she said via email.

The revelation comes the same day the Navy released a 69-page report about physiological episodes that have affected the crews of Hornets, Growlers, and

trainers. Commissioned after the Navy ordered a pause in T-45 training flights due to a spike in cockpit episodes, the report offers abundant data, but few solutions.

Documents released alongside the report show that the Hornet and Growler communities saw a record spike in episodes in 2016, with 125 incidents reported. Data for 2017 suggests another notable year, with 52 incidents reported just since January.

For the T-45, cockpit episodes spiked in 2015 and have stayed high since, with a record number, 36, in 2016, and 21 so far this year. March 2017 was a record month for T-45 incidents, with ten reported across the three training units that fly the aircraft.

While those in the T-45 community have speculated that mysterious hypoxia-like episodes in the cockpit are caused by a contaminant on the aircraft's onboard oxygen generation system, most F/A-18 episodes have been attributed to environmental control system issues and cabin pressurization malfunctions, according to the report.

And that's where the watches may come in handy.

The watches, the report notes, were purchased for all F/A-18 crew based in

, Virginia, because the cabin altimeter gauge of their aircraft was difficult to read due to its size and location, and "its audible warnings are ineffective through the flight envelope."

The watches, once issued to pilots, will alert them when cabin altitude reaches a preset threshold, Navy spokeswoman Lt. Kara Yingling told Military.com. Essentially, the devices could provide pilots with an additional early warning to prevent cabin pressure problems from reaching a crisis point.

to conduct airstrikes on Islamic State targets in Iraq and Syria. Capt. James McCall, commander of Carrier Air Wing 8 deployed aboard the carrier George H. W. Bush, said the idea had originated with the crew of VFA-37. The Navy then authorized them to wear the devices, he said.

"I can't speak to the Navy enterprise, their intention to do that for all type-model-series, but I know our guys wear them and like the capability they provide," McCall said.

As of May, two Hornet pilots assigned to the Bush had experienced physiological episodes during missions, McCall said at the time. They were treated using another innovation: a recompression chamber that deployed aboard the Bush for just that purpose.

The altimeter watch concept does have its detractors, however.

"These watches have not undergone [Naval Air Systems Command] testing for accuracy and dynamic range for this application," the authors of the new report warn. "NAVAIR engineers expressed concern these watches could provide a false sense of security."

Navy officials continue to look for ways to solve the problem of physiological episodes -- an issue that has claimed the lives of four Hornet pilots over the course of decades, according to recently released data.

Vice Chief of Naval Operations Adm. Bill Moran, who ordered the recent review, told reporters Thursday that a slew of efforts were still underway to detect existing problems and to ensure that onboard oxygen generation systems were providing pilots with clean, dry, non-contaminated air. If all else fails, the Navy may order aircraft to be equipped across the board with a new, next-generation onboard oxygen generation system, Moran said.

We have been dealing with hypoxic events in naval aviation for as long as we've had high-performance jets," Moran said. "What we're seeing, though, is a trend in the wrong direction."

Understand it is a busy water way but how could this possibly happen to such a high tech warship with state of the art surface search radars and sailors on watch. Hope no one is seriously hurt.
Exactly Smileys perplexe.PNG but in the night etc... surely a reason what ?
Make sense crew counter-flooding it repair to Yokosuka her homeport but enough big damage structurals also surely several months needed.

For damages mass reason the cargo much more big... fault to ? for insurances.

Official report


USS Fitzgerald Returns to Yokosuka

USS Fitzgerald (DDG 62), aided by tug boats, returned to Yokosuka at 6:15 p.m. this evening.

Approximately 16 hours earlier, it was involved in a collision with the Philippine-flagged merchant vessel ACX Crystal while operating about 56 nautical miles southwest of Yokosuka, Japan. Seven of Fitzgerald's crew remain missing.

Vice Adm. Joseph P. Aucoin, commander, U.S. 7th Fleet, along with many family members, were on the pier when the ship arrived.

"This has been a difficult day," Aucoin said. "I am humbled by the bravery and tenacity of the Fitzgerald crew. Now that the ship is in Yokosuka, I ask that you help the families by maintaining their privacy as we continue the search for our shipmates."

"I want to highlight the extraordinary courage of the Fitzgerald Sailors who contained the flooding, stabilized the ship and sailed her back to Yokosuka despite the exceptionally trying circumstances," said Rear Adm. Charles Williams, commander, Task Force 70.

Shortly after the collision the U.S. made a request for support from the Japan Coast Guard (JCG), which were the first on scene and continues to be lead for search and rescue efforts. The Japan Maritime Self-Defense Force (JMSDF) ships JS Ohnami, JS Hamagiri, and JS Enshu were sent to join the JCG ships Izanami and Kano. USS Dewey (DDG 105) served as an escort for Fitzgerald and has also returned to Yokosuka. A U.S. P-8 Poseidon aircraft is working in concert with two JMSDF Helicopters and a JMSDF P-3 Orion aircraft to search the area. Names of the missing Sailors are being withheld until the families have been notified.

The collision affected Fitzgerald's forward starboard side above and below the water line, causing significant damage and associated flooding to two berthing spaces, a machinery space and the radio room, which damage control teams quickly began dewatering. Though the ship is back in Yokosuka it remains uncertain as to how long it will take to gain access to the spaces in order to methodically continue the search for the missing.

Once the ship arrived in Yokosuka, divers began inspecting the damage and developing a plan for repairs and inspection of the spaces.

Three patients required medical evacuation from the ship. One was Cmdr. Bryce Benson, Fitzgerald's commanding officer, who was transferred to U.S. Naval Hospital Yokosuka by a JMSDF helicopter. All three Sailors are awake and will remain under observation at the hospital until further notice. Other injured are being assessed.

The USS Fitzgerald Emergency Family Assistance Center will remain open for chaplain and counselor care indefinitely, 24/7, on the Command Readiness Center's 4th floor (across from the commissary) - in the same classroom where the Area Orientation Brief (AOB) is hosted.

and US Navy seeks next-generation oxygen system for T-45s
The US Navy and industry will pursue a next-generation on board oxygen generator system (OBOGS) while the service implements fixes to mitigate persistent oxygen and pressurization issues on its Boeing/BAE Systems T-45 trainers and Boeing F/A-18E/F Super Hornets.

Following a comprehensive review of physiological events on the T-45 Goshawks and F/A-18E/F fighters, the navy concluded the OBOGS on both aircraft are not able to provide clean, dry air to pilots and can even allow contaminants to escape into their breathing air that can cause hypoxia. The navy found pressurization issues caused most of the oxygen problems for F/A-18E/F pilots, while the OBOGS emerged as the culprit on T-45s,

In a 15 June call with reporters, vice chief of naval operations Adm Bill Moran admitted that while the report found issues with the OBOGS and the F/A-18E/F’s environmental control system, which provide air for pressurization, heating and cooling, the root cause of hypoxia remains elusive.

“Root cause to me is if you identify a specific system or event or environmental condition that causes a hypoxic event or a pressurization malfunction,” Moran says. “When I say we haven’t found the cause, it may be more than one component or condition that clearly leads to a physiological event. So what we’re doing is systematically going after anything that contributes to the cleanliness, the dryness and pressure of air at any stage of ground or flight operations.”

However, the navy’s review team discovered T-45's OBOGS does not have a water separator mechanism, even though the service fields a similar mechanism on OBOGS in high performance jets, Moran says. When water interacts with contaminants in the OBOGS, it can release the contaminants into the aircrew breathing air. The navy will install water separators on T-45s by this fall, Moran says.

In parallel with ongoing mitigation efforts, industry will install breathing air pressure warning for aircraft fitted with the solid state oxygen monitor (CRU-123) this month and develop a next-generation OBOGS known as GGU-25.

T-45’s current OBOGS is made up of Cobham’s oxygen concentrator (GGU-7), an oxygen monitor (CRU-99) and an aircrew-worn breathing air regulator (CRU- 103).

The CRU-123 is a digital upgrade to the current CRU-99 and will be able to deliver information on both temperature and oxygen pressure to pilots, Moran says. Cobham is looking at the redesigned OBOGS as a potential replacement for the legacy system if the navy’s mitigation efforts do not work, he adds. The effort also includes adding a larger capacity emergency oxygen system on the T-45 to eliminate the current way the navy uses on board oxygen today.

“So we’re doing all that in parallel,” Moran says. “We’re not waiting for next-generation or a complete redesign which will take quite a bit longer we’re installing some mitigation measures.”

Meanwhile, the Navy is sharing its findings on hypoxia issues with the US Air Force, which recently experienced oxygen problems on Lockheed Martin F-35As at Luke Air Force Base, Arizona. The Defense Department has asked the navy for information on the hypoxia study and will determine whether the F-35 effort should merit an independent or can follow on the navy’s effort, Moran says.

The crew is trained to contain the flooding and stabilize the ship were it to be damaged in combat. These circumstances were less extreme and I would expect that no "extraordinary courage" was demanded of the crew.
