Bath Iron Works this week celebrated the keel laying for its latest warship, the USS Louis H. Wilson Jr.
It’s the shipyard’s first Flight III Arleigh Burke-class destroyer, which includes an advanced radar system. The ship’s namesake was a Marine Corps general from Mississippi who fought in World War II and earned a Medal of Honor during the Battle of Guam in 1944. Wilson died in 2005.

Wilson’s daughter, Janet Wilson Taylor, attended the keel-laying ceremony Tuesday and authenticated it by striking welding arcs on a steel plate that will be incorporated into the ship.

“The skill and hard work of our shipbuilding team are making (the USS Louis H. Wilson Jr.) a ship we can be proud to say is Bath built,” said BIW President Chuck Krugh in a statement. “When it sails down the Kennebec River, this ship will be ready to carry out its mission of protecting our nation and our families just as its namesake, Louis H. Wilson Jr., did throughout his distinguished career.”

Navy Capt. Seth Miller, the Arleigh Burke destroyer program manager, added, “We are proud to reach this important milestone in the production of the future USS Louis H. Wilson Jr. This great warship will carry the legacy of General Wilson’s unwavering commitment and service to our country.”

BIW [started building the USS Louis H. Wilson Jr. in 2020]('https://www.pressherald.com/2020/03/05/biw-begins-work-on-latest-destroyer/'). It should be ready for sea trials in about two years, according to BIW spokesperson David Hench.

The ship will feature Raytheon’s new SPY-6 radar, which the company says is the most advanced naval radar in the world. Raytheon said the radar can detect ballistic missiles, cruise missiles, aircraft and surface ships simultaneously.

“It’s a vast improvement over what the U.S. Navy currently has on it ships,” said Kim Ernzen, Raytheon’s president of naval power, in a statement on the company’s website. “It’s like going from a pen light to a huge flashlight.”
The USS Louis H. Wilson Jr. will be the Navy’s second Flight III destroyer. The first, the USS Jack H. Lucas, was built at Ingalls Shipbuilding in Pascagoula, Mississippi, and launched in 2021. BIW and Ingalls Shipbuilding are the only shipyards that build Arleigh Burke-class destroyers, which carry missiles, torpedoes and have room for two helicopters. The roughly 500-foot ships have a crew of about 400.

The USS Louis H. Wilson Jr. is one of six destroyers under construction at BIW. The shipyard’s production in the last few years has been slowed by the coronavirus pandemic and a union strike, though last month Admiral Mike Gilday, U.S. chief of naval operations, [visited and said production has been ramping back up]('https://www.pressherald.com/2023/04/24/biw-destroyer-production-ramping-up-after-delays-admiral-says/'). He said workers are 30%-60% ahead of schedule in some production phases.

BIW’s most recently completed destroyer, the USS Carl M. Levin, will be commissioned June 24 before heading to its home port in Hawaii to patrol the western Pacific Ocean.

Sens. Susan Collins and Angus King have been lobbying for the construction of more destroyers, saying they are the workhorse of the Navy and an important bulwark against China’s growing naval fleet. Collins, vice chairperson of the Appropriations Committee and ranking member of the Defense Appropriations Subcommittee, helped secure funding for three new destroyers in the next fiscal year, but the Navy decided to purchase only two [over concerns about production delays]('https://www.pressherald.com/2023/04/03/bath-iron-works-mississippi-shipyard-cant-produce-destroyers-fast-enough-navy-says/'). The $858 billion defense bill that President Joe Biden signed in September gives the Navy the option to purchase 15 destroyers over the next five years.

BIW, which employs about 6,500, is working with Ingalls Shipbuilding on the design for the next-generation destroyer, the DDG(X), which would replace the Arleigh Burke destroyers. The new destroyers are expected to have lasers and hypersonic missiles.

[HEADING=2][SIZE=7]Voyager 1 Is Returning a Mishmash of 1s And 0s From Space. NASA Is Baffled.[/SIZE][/HEADING]
[SIZE=7]attachment 72269[/SIZE]
[Voyager 1]('https://voyager.jpl.nasa.gov/'), the most distant human-made object from Earth, is sending back a repetitive jumble of 1s and 0s that don't make any sense.

Scientists at NASA are desperately trying to fix the glitch from 24 billion kilometers (15 billion miles) away.

The probe can still receive commands from Earth but messages to interstellar space require approximately 22.5 hours of travel.

That means it will take days before experts know if their attempts to restore the probe's nearly 50-year-old computers have worked or not.

This isn't the first time that Voyager 1 has sent back [random readouts]('https://www.universetoday.com/156065/voyager-1-doesnt-know-where-it-is-generating-random-looking-telemetry-data/'). In 2022, the probe started returning some of its data through a broken computer onboard, corrupting the outgoing messages.

Engineers at NASA managed to figure the problem out and fix it. But it took [several months]('https://www.universetoday.com/157378/problem-solved-voyager-1-is-no-longer-sending-home-garbled-data/').

In this case, the glitch is [coming from a disruption in communication]('https://blogs.nasa.gov/sunspot/') between one of three computers onboard, called the probe's flight data system (FDS), and one of the probe's subsystems: the telemetry modulation unit (TMU).

This means that no science data about interstellar space is returning to Earth. What's more, engineering data describing the health and status of the probe is also a jumbled mess.

And yes, before you ask, engineers have tried turning the FDS on and off.

A team at NASA are now pouring through decades old documents on how the probe and its computers work – extremely outdated technology that has been all but forgotten.

Today, the phone in your hand can handle more than [100 billion instructions a second]('https://en.wikipedia.org/wiki/Instructions_per_second'). The Voyager's computers can process just [8,000 a second]('https://voyager.jpl.nasa.gov/frequently-asked-questions/').

The mission was really never meant to last this long. Both the Voyager 1 and Voyager 2 probes, which were [launched in close succession in 1977]('https://voyager.jpl.nasa.gov/mission/'), were mainly designed to explore [Jupiter]('https://www.sciencealert.com/the-weirdest-facts-about-jupiter') and [Saturn]('https://www.sciencealert.com/what-is-saturn'). They are now zooming further and further away from us through interstellar space.

Putting another probe in the same spot would require decades.

If Voyager 1's outgoing data can be fixed, scientists hope it can continue until the mission's 50th birthday.

But its days are numbered. Beyond the Oort Cloud, on the distant edges of the Kuiper Belt, both probes will [inevitably fall silent]('https://www.popsci.com/story/science/nasa-voyager-1-final-days/?amp') as the power of their generators run out of juice.

Cool picture of the Merlin Airplane Engine production facility. The Merlin powered nearly the entire line of RAF fighters and smaller bombers, including the planes that won the Battle of Britain, the Hurricane and Spitfire, along with the USAAC's premier fighter, the P-51 Mustang.

attachment 75305

The Rolls-Royce Merlin is a British [liquid-cooled]('https://en.wikipedia.org/wiki/Coolant#Liquids') [V-12]('https://en.wikipedia.org/wiki/V12_engine') [piston]('https://en.wikipedia.org/wiki/Reciprocating_engine') [aero engine]('https://en.wikipedia.org/wiki/Aero_engine') of 27-litres (1,650 cu in) [capacity]('https://en.wikipedia.org/wiki/Engine_displacement'). [Rolls-Royce]('https://en.wikipedia.org/wiki/Rolls-Royce_Limited') designed the engine and first ran it in 1933 as a private venture. Initially known as the PV-12, it was later called [Merlin]('https://en.wikipedia.org/wiki/Merlin_(bird)') following the company convention of naming its four-stroke piston aero engines after [birds of prey]('https://en.wikipedia.org/wiki/Birds_of_prey').

After several modifications, the first production variants of the PV-12 were completed in 1936. The first operational aircraft to enter service using the Merlin were the [Fairey Battle]('https://en.wikipedia.org/wiki/Fairey_Battle'), [Hawker Hurricane]('https://en.wikipedia.org/wiki/Hawker_Hurricane') and [Supermarine Spitfire]('https://en.wikipedia.org/wiki/Supermarine_Spitfire'). The Merlin remains most closely associated with the Spitfire and Hurricane, although the majority of the production run was for the four-engined [Avro Lancaster]('https://en.wikipedia.org/wiki/Avro_Lancaster') heavy bomber. A series of rapidly-applied developments, brought about by wartime needs, markedly improved the engine's performance and durability. Starting at 1,000 horsepower (750 kW) for the first production models, most late war versions produced just under 1,800 horsepower (1,300 kW), and the very latest version as used in the [de Havilland Hornet]('https://en.wikipedia.org/wiki/De_Havilland_Hornet') over 2,000 horsepower (1,500 kW).

One of the most successful aircraft engines of the World War II era, some 50 versions of the Merlin were built by Rolls-Royce in [Derby]('https://en.wikipedia.org/wiki/Derby'), [Crewe]('https://en.wikipedia.org/wiki/Crewe') and [Glasgow]('https://en.wikipedia.org/wiki/Glasgow'), as well as by [Ford of Britain]('https://en.wikipedia.org/wiki/Ford_of_Britain') at their [Trafford Park factory]('https://en.wikipedia.org/wiki/Ford_Trafford_Park_Factory'), near [Manchester]('https://en.wikipedia.org/wiki/Manchester'). A de-rated version was also the basis of the [Rolls-Royce/Rover Meteor]('https://en.wikipedia.org/wiki/Rolls-Royce_Meteor') tank engine. Post-war, the Merlin was largely superseded by the [Rolls-Royce Griffon]('https://en.wikipedia.org/wiki/Rolls-Royce_Griffon') for military use, with most Merlin variants being designed and built for [airliners]('https://en.wikipedia.org/wiki/Airliner') and [military transport aircraft]('https://en.wikipedia.org/wiki/Military_transport_aircraft').

The [Packard V-1650]('https://en.wikipedia.org/wiki/Packard_V-1650') was a version of the Merlin built in the United States. Production ceased in 1950 after a total of almost 150,000 engines had been delivered. Merlin engines remain in [Royal Air Force]('https://en.wikipedia.org/wiki/Royal_Air_Force') service today with the [Battle of Britain Memorial Flight]('https://en.wikipedia.org/wiki/Battle_of_Britain_Memorial_Flight'), and power many restored aircraft in private ownership worldwide.
