Loocas,
Predelagam da pogledaš koliko je US dala v razvoj laserkega in rail gun programa proti koliko je letos USA dala za budget samo za razvoj ekvivalenta Kitajskim in ruskim konzervam, ki letijo nad 1000km/s

Samo tele kitajsko-ruske so pa vsakič nekaj bolj norega. Še prejšnji teden so bile visoko okretne pri pičlih 2 km/s, zdaj je 1000 km/s že kar standard. No, vsaj nekaj - če je na tem 1% resnice bomo najkasneje do leta 2020 imeli intergalaktična plovila z nadsvetlobno hitrostjo.

Lahko gre tudi za nabijanje. Žal je to bolj verjetno

novejše klase bodo očitno imele za velikostni razred več električne moči. zumwalt ima 78MW generator.

Predvsem je razlika v načinu pogona. Arleigh Burke ima konvencionalen pogon, kjer motor poganja gred ladijskega vijaka, Zumwalt pa generatorje v drobovju ladje in električne motorje, ki poganjajo vijake (vsaj del izven lupine za večjo okretnost). Posledica tega je, da ladja po potrebi lahko razpolaga tudi z neprimerno več električne energije in za Zumwalta tudi 20 MW laser ne bi bil nek zalogaj. Ladja bi plula nekaj počasneje, to je pa tudi vse.

pa recimo pogonska gred turbine na f-35 razvije 20 MW.

Da, za vojsko 1 MW moči ni nek velik zalogaj. M1A2 ima motor moči 1,1 MW.

Oprosti smrekar, samm typo kar ti je la#je 1000m/s ali 1km/s.

No, napredujemo.

In da še vedno ne znaš izračunati koliko energije je potrebno za 1 MW laser.

Tako je. Dokler ne poveš koliko časa naj ta laser sveti namreč ne morem nikakor izračunati koliko energije bom za to porabil. Če ne razumeš počakaj, da boste v šoli to jemali.

Laser je hudič, moraš pumpat vanj do 2ox več energije kot je output.
Nisem prepričan, da je izkoristek danes čez 7%.

85% izkoristek pri -50°C, 76% pri 10°C, 10 let nazaj.

It’s been a good year for hypersonic researchers, who got a 50 percent bump in the Defense Department’s 2017 budget request. The Air Force plans to test a hypersonic missile by the end of the decade.

Smrekar1, škoda da niso za Zumwalte uporabili jederskih reaktorjev...

Invictus je 1. jul 2016 ob 11:42 izjavil:

Jedrski reaktorji se v US Navy uporabljajo samo za letalonosilke in podmornice.

Pri ostalih so šli na konvencionalni pogon, kar se mi zdi precej butasta ideja za ladje, ki spremljajo letalonosilko.

Praktično jih je treba tankati na par dni, če je malo več akcije. Sam zdaj ne najdem linka... Nisem verjel da pokurijo toliko nafte, ko sem bral članek.

Invictus je 1. jul 2016 ob 11:55 izjavil:

Sam vseeno. Američani imajo dober jedrski reaktor v podmornicah tipa Virginia. Narejen za 50 let brez vzdrževanja.

Zakaj ga niso ponucali na Zumwaltu, nimam pojma. 2x ali 3x po 30MW bi bilo več kot dovolj...

Mr.B je 23. jun 2016 ob 19:00 izjavil:

Seveda jo bodo, no jo že imajo, pa Indijci in kitajci tudi. Mapka že tako vemo, da ta laser razen za neke osnovne gretje ladje ni primeren. Sicer pa nobena moderna raketa razen v zadnji fazi, ko je že prepozno ne uporablja elektroniki v nosu. Žal pa razen v nos, teh raket res ne moreš streljat.

Loocas je 3. jul 2016 ob 17:37 izjavil:

toliko o tem, kdaj bodo te rakete na voljo:
http://nextbigfuture.com/2016/07/curren...

China could deploy hypersonic boost and glide missile by 2020 and hypersonic powered missiles by 2025
Russian hypersonic Zircon missiles by 2022
Russia and India want to have a shortrange almost-hypersonic missile by 2020 and a mach 7+ version by 2029

Kako se bodo razvili laserji do 2025 pa lahko samo predvidevamo...

Ne, ker v tem trenutku ni potreb.

A couple of weeks ago, I ran across a really interesting story from Operation Desert Storm. Did you know the United States deployed a Ground-Launched Cruise Missile (GLCM) unit in Saudi Arabia? But, instead of being equipped with nuclear-armed BGM-109G Gryphon, the unit deployed with Navy BQM-74 Chukar drones that were used to spoof the radars associated with Iraq’s air defenses. The operation, known as Scathe Mean, is really interesting tale.

...

The short version is that the Air Force wanted to send a wave of target drones into Iraq to fool the Iraqis into turning on their radars, with a large number of strike aircraft following to, uh, turn them back off permanently.

In 2002, Albania announced that it had discovered 16 tons of Chinese supplied chemical weapons dating to the dictatorship of Enver Hoxha at a bunker near Qafëmollë (sometimes rendered as Qaf Molle). Here are some pictures of the bunker and the munitions, which is located at: 41°20’43.36″N, 19°57’21.90″E

Tirana appealed for help.

...

The United States, thanks to the leadership of then-Senator Richard Lugar, ultimately paid for security at the site, including fences and armed guards, as well as for deployment of a mobile incinerator. DTRA contracted with Eisenmann AG for the incinerator unit and URS to manage the project.

...

The United States, according to Bob Mikulak, ultimately “contributed over 45 million dollars to assist the Republic of Albania in eliminating 16.6 metric tons of chemical weapons agents at Qaf Molle, destroying 100 percent of its stockpile in a verified manner” by July 2007.

Sadly, that’s not the end of the story. Here we pick up the story based on cables from Wikileaks. What about all the hazardous waste?

The Albanian Ministry of Defense had agreed to take it, planning to construct a hazardous waste storage facility with assistance from the European Union. That process went nowhere. The US complained to the Europeans, but the EU canceled the project in the wake of local opposition.

The hazardous waste sat in containers on the concrete pad. The containers started to leak. In late 2007-early 2008, the US hired an environmental remediation firm, Savant Environmental, “who determined the problem was worse than originally thought. Many of the containers were leaking salts of heavy metals, primarily arsenic, lead and mercury. In addition, the conexes were not waterproof, and since contaminated components had not been properly cleaned before being put into the conexes, condensation and water leakage were dissolving some of the contaminants and causing them to leak out onto the ground.”

Savant Environmental repackaged the waste and placed it in 20 shipping containers. There it sits, visible from space. Good for twenty years. Well, fifteen now. Ish.

Those containers are still sitting on the concrete pad, out in the open. Here is a satellite image from August.

...

The stuff isn’t a chemical weapons threat any more, of course, but it is an environmental hazard. Just sitting in some shipping containers.

...

I realize that individual states have to take some responsibility, but if we’re going to argue that nonproliferation is shared interest we can’t say the hazardous waste from chemical weapon demilitarization or disposing of seized munitions aren’t part of our shared responsibility.

I don’t want to leave the impression that I am criticizing the Defense Threat Reduction Agency, which did more than anyone else in this saga save for maybe Dick Lugar and staff. They can’t do it all, for goodness sake. And lord knows, pressing for US assistance to Albania didn’t help Lugar win his primary. It would be nice if the Europeans stepped up on the construction of a hazardous waste facility in Albania or the Chinese agreed to make amends for selling a nasty government some nasty weapons. Or even the Russians, for propping up Joe Stalin’s buddy. I know Wikileaks hates the United States, but those leaked cables suggest Washington worked harder than any other country — even if the US wasn’t perfect all the time. The Italians complained about the risk from the site, but what did they offer?

Maybe Albania is no worse off than if it had left the chemical weapons rotting in the bunker, slowly poisoning the hillside — but that setts the bar pretty low. If we want to persuade states to take, for example, Syria’s chemical weapons stockpiles, it would help if Albania’s story had a happy ending. And we — not just Americans, but everyone who cares about nonproliferation — should take special care that whatever country takes Syria’s chemical weapons stockpile isn’t left regretting that decision.

The U.S. Air Force on Tuesday declared an initial squadron of Lockheed Martin Corp (LMT.N) F-35A fighter jets ready for combat, marking a major milestone for a program that has faced cost overruns and delays.

...

"The U.S. Air Force decision to make the 15 F-35As at Hill Air Force Base combat ready sends a simple and powerful message to America's friends and foes alike - the F-35 can do its mission," F-35 program chief, Air Force Lieutenant General Chris Bogdan, said in a statement.

...

Industry and U.S. defense officials say they are working hard to continue driving down the cost of the new warplanes to around $85 million per plane by 2019, as well as the cost of operating the jets.

The Indian Navy's primary fighter operating from the aircraft carrier INS Vikramaditya faces operational deficiencies due to defects in engines, airframes and fly-by-wire systems, according to a report by India's autonomous auditor, the Comptroller and Auditor General (CAG). However, Indian Navy officials say the Russian-made MiG-29K remains the best choice available.

The report said the "aircraft MiG-29K is being technically accepted despite having discrepancies and anomalies."

...

On problems with the engine, the CAG report said: "Since induction in February 2010, 40 engines (62 percent) of twin-engined MiG-29K have been withdrawn from service/rejected due to design-related defects."

Additionally, the serviceability of the warplanes was low, ranging from 21.30 percent to 47.14 percent, according to the report.

"The roots of these problems (serviceability and defects) lie in the extremely poor quality control in the Russian military-industrial complex and dismal product support being rendered by the Russian industry to the Indian Navy for the past 25 years," Prakash said. "This is in spite of the fact that the development of the MiG-29K has been totally funded by the Indian Navy."

...

"The engine-design defects should be rectified with the utmost urgency at the Russians' cost," Prakash said. "Any respectable company, conscious of its reputation, would attend to this. But the oligarchs who control the Russian military-industrial complex are too brazen, for two reasons: (a) they know that India has not choice and (b) they are confident that Indian politicians will never turn the screw on them."

This crazy bastard had so many ways to kill you, it was like a death buffet: should I die in the nuclear blasts of the bombs themselves, or just let the shockwave of the overpassing missile kill me? Maybe I’ll just wait for the radiation sickness as this thing circles endlessly overhead, like a colossal demonic robot vulture. It’s so hard to choose!
