Trumps orders Pentagon to create US 'Space Force'

US President Donald Trump ordered the Pentagon on 18 June to create a new US ‘Space Force’, which would become the sixth branch of the American military but which requires Congressional approval to take effect.
Trump said: ‘I'm hereby directing the Department of Defense and Pentagon to immediately begin the process necessary to establish a Space Force as the sixth branch of the armed forces. We are going to have the Air Force, and we are going to have the Space Force, separate but equal.’
Details about the role and timing of any new space force were not immediately clear.
However, the creation of a new branch of the military cannot happen from one day to the next, as Congress would have to pass a law authorising it first.
Trump has previously supported the idea of creating a sixth branch of the armed forces, adding to the US Army, Air Force, Marines, Navy and Coast Guard.
Debate over the issue has raged in Congress for years, with some supportive of the idea and others insisting space duties remain under the Air Force as they are now.
At the start of the third meeting of the National Space Council, an advisory body led by Vice President Mike Pence, Trump said: ‘When it comes to defending America it is not enough to merely have an American presence in space, we must have American dominance in space.’
Trump also signed a directive on space traffic management, aimed at boosting public-private monitoring of objects in orbit so as to avoid collisions and debris strikes.
A statement released by the White House said the move ‘seeks to reduce the growing threat of orbital debris to the common interest of all nations.’

Les États-Unis développent un obusier tracté M777ER, capable de frapper des cibles à plus de 70 km de distance. Selon les médias occidentaux, le pentagone s'attend à surpasser les systèmes d'artillerie russes Msta-S et Coalitsiya-SV

Upgrading US Navy ships is difficult and expensive. Change is coming.

WASHINGTON ― The U.S. Navy is looking at extending the life of its surface ships by as much as 13 years, meaning some ships might be 53 years old when they leave the fleet.


Here’s the main problem: keeping their combat systems relevant.

The Navy’s front-line combatants ― cruisers and destroyers ― are incredibly expensive to upgrade, in part because one must cut open the ship and remove fixtures that were intended to be permanent when they were installed.

When the Navy put Baseline 9 on the cruiser Normandy a few years ago, which included all new consoles, displays and computer servers in addition to the software, it ran the service $188 million.

Now, the capability and function of the new Baseline 9 suite on Normandy is staggering. The cost of doing that to all the legacy cruisers and destroyers in the fleet would be equally staggering: it would cost billions.

So why is that? Why are the most advanced ships on the planet so difficult to keep relevant? And if the pace of change is picking up, how can the Navy stay relevant in the future without breaking the national piggy bank?

Capt. Mark Vandroff, the current commanding officer of the Carderock Division of the Naval Surface Warfare Center and former Arleigh Burke-class destroyer program manager, understands this issue better than most. At this week’s American Society of Naval Engineers symposium, Vandroff described why its so darn hard to upgrade the old ships and how future designs will do better.

Here’s what Vandroff had to say:

“Flexibility is a requirement that historically we haven’t valued, and we haven’t valued it for very good reasons: It wasn’t important.

“When you think of a ship that was designed in the ‘70s and built in the ‘80s, we didn’t realize how fast and how much technology was going to change. We could have said: ‘You know what? I’m going to have everything bolted.’ Bolt down the consoles in [the combat information center], bolt in the [vertical launch system] launchers ― all of it bolted so that we could more easily pop out and remove and switch out.

“The problem was we didn’t value that back then. We were told to value survivability and density because we were trying to pack maximum capability into the space that we have. That’s why you have what you have with the DDG-51 today. And they are hard to modernize because we valued survivability and packing the maximum capability into the minimum space. And we achieved that because that was the requirement at the time.

“I would argue that now as we look at requirements for future ships, flexibility is a priority. You are going to have to balance it. What if I have to bolt stuff down? Well, either we are going to give up some of my survivability standards or I’m going to take up more space to have the equivalent standards with an different kind of mounting system, for example. And that is going to generate a new set of requirements ― it’s going to drive design in different directions than it went before.

“I suppose you could accuse the ship designers in the 1980s of failure to foresee the future, but that’s all of us. And the point is they did what they were told to do. Flexibility is what we want now, and I think you will see it drive design from this point forward because it is now something we are forced to value.”

Navy Columbia-Class submarine quieting 'electric drive' - stealthiest sub ever?

The Navy has now issued at least one-fourth of the design work and begun further advancing work on systems such as a stealthy "electric drive" propulsion system for the emerging nuclear-armed Columbia-Class ballistic missile submarines by 2021.

“Of the required design disclosures (drawings), 26-percent have been issued, and the program is on a path to have 83-percent issued by construction start,” Bill Couch, spokesman for Naval Sea Systems Command, told Warrior Maven.

The Columbia class is to be equipped with an electric-drive propulsion train, as opposed to the mechanical-drive propulsion train used on other Navy submarines.

In today’s Ohio-class submarines, a reactor plant generates heat which creates steam, Navy officials explained. The steam then turns turbines which produce electricity and also propel the ship forward through “reduction gears” which are able to translate the high-speed energy from a turbine into the shaft RPMs needed to move a boat propeller.

“The electric-drive system is expected to be quieter (i.e., stealthier) than a mechanical-drive system,” a Congressional Research Service report on Columbia-Class submarines from earlier this year states.....

SpaceX Just Sold the US Air Force the Cheapest Enormous Rocket It’s Ever Bought

launch will cost $130 million, far less than the $350 million average cost of United Launch Alliance’s Delta IV.


SpaceX has won its first contract to launch a classified military satellite on its Falcon Heavy rocket, beating out rival United Launch Alliance, a joint venture of Lockheed Martin and Boeing.

The launch contract will cost the U.S. Air Force $130 million, far less than the $350 million average cost of United Launch Alliance’s Delta IV, previously the heaviest lifter in the U.S. arsenal. SpaceX’s disruptive business model has proven itself in the national security arena, where it has won five previous contracts since its rockets were certified to fly military missions.

The U.S. Air Force decision signals confidence in the engineering behind the new rocket, which consists of three modified Falcon 9 cores strapped together and flew for the first time in February 2018 after seven years of development and testing.

“On behalf of all of our employees, I want to thank the Air Force for certifying Falcon Heavy, awarding us this critically important mission, and for their trust and confidence in our company,” SpaceX president Gwynne Shotwell said in a statement. “SpaceX is pleased to continue offering the American taxpayer the most cost-effective, reliable launch services for vital national security space missions.”

quelque consideration interessants US
What’s going on with America’s next fighter designs?
.......Notably, the Pentagon’s recently released 30-year aviation plan shows the Air Force intends to complete its analysis of alternatives in the summer of 2018, with the Navy completing its equivalent in mid-2019.

That could be a sign that the systems will share some technologies. There are likely some shared technologies between the two, including things like directed energy or artifical intelligence, which brings back the core question of what a next-generation fighter looks like, and if it is as much a fighter plane as a hub for sensors and “loyal wingman” drones. And in 2015, then-acquisistion head Frank Kendall said the two systems would involve common parts.

But regardless of the final product, the design of the program won’t look anything like the multi-service, multinational F-35 fighter jet.

Sixth-Gen Fighter Likely Won’t Be Common Across Services, Air Force General Says
In a departure from the dual-service F-35 effort, the Pentagon’s sixth-generation fighter jet likely won’t be common between the US Air Force and the US Navy, a top Air Force general said Friday.

By: Lara Seligman, Phillip Swarts
That includes nixing the potential that the American designs could somehow join forces with the two potential European fighter designs under consideration: one from a Franco-German team-up, and another from the United Kingdom.

“The F-35 experience has effectively killed jointness and international partnerships, for now at least,” said Richard Aboulafia, an analyst with the Teal Group.

That may be the right approach if the U.S. is truly concerned about security, noted Callan.

“The F-35 is a compromised design in a lot of ways,” Callan said
. “You have to assume the Chinese know a lot about that plane from what they’ve been able to siphon off from theft or cyber means. There may be less incentive for U.S. to partner on a program like this if the goal is to have something that is really technological[ly] advanced and unique. The bigger the partnership, the more potential leakage points.”

However, keeping a program entirely domestic could present long-term economic challenges, he noted.

“That may be good, that may be bad. It could be like the F-22 — end up with 100-plus phenomenally expensive planes but no export market. So, pick your poison.
