It is near to heresy to argue that the US military would have budget problems. They will have all sort of problems like corruption, inefficiency, and immoral behavior but they will not have money issues.
What do they want more? Trump just increased their budget for 60 billion USD?
Heck, when they cannot call it a failure, they give it a nicer name, this time, budgetary constraints.
Pathetic.

I just wanna highlight two main points briefly:
1) As long as the PETRODOLLAR Regime still prevails (thus propping the WRC status of the usd), it is NOT possible for the USG to run out of money (dollars), at least not at where it really matters for them.
(Unless one does believe that they are having some problem with their "printing press"
)2) The widespread FALLACY that it is not possible for the U.S. to be hindered by the technical/technological deficiencies due to its superiority in technological base!
Say it in other words, everything that every other nation can master, the U.S. should be able to. Only the physics that can limit their achievements. And this conjecture is the widely hold perception, even among the forum members here, let alone the general populace. The Hollywood and their media dominance definitely have their own credits here.

New motor to be used for classified weaponry
2018-06-20 09:43:06 Global Times Editor : Li Yan
China has produced a new type of electric motor that would meet the heavy demand from China's latest electromagnetic weapon system, which may involve electromagnetic railgun and ballistic missile technologies, said an expert.
Academy of Aerospace Solid Propulsion Technology under China Aerospace Science and Technology Corporation has recently delivered a batch of newly developed brushed DC electric motors to an unnamed unit. The motors will be used in China's latest electromagnetic weapon system and are under heavy demand, reads an article published by the academy on WeChat on June 10.
The new motors can operate in special environments including in high-intensity magnetic fields and are resistant to strong blasts, according to the article.
A staff member in charge of publicity at the academy confirmed the news to the Global Times on Tuesday but refused to provide further information.
The delivery marks China's constant improvement on DC electric motors, Song Zhongping, a military expert and TV commentator, told the Global Times on Tuesday, noting the recent technological advancement was a challenging one.
The electromagnetic weapon system that needs the motors might be China's electromagnetic railgun. Other weapons that need a servo mechanism, such as ballistic missiles, may also require such motors, said Song.
The Chinese Navy will likely be the first in China to equip vehicles with an electromagnetic railgun. Type 055, China's first domestically developed 10,000-ton class missile destroyer, would be a great fit, said Song.
Photos spread on the internet since January 30 showed that a Type 072 III landing ship of the People's Liberation Army Navy was equipped with a main gun that is suspected to be an experimental electromagnetic railgun, reported Science and Technology Daily on February 5.
An electromagnetic railgun can fire projectiles via electromagnetic force at incredibly destructive velocity. It can reach farther ranges compared with standard artillery and maintain high accuracy, said Song.
However, the words "heavy demand" does not necessarily mean that China's electromagnetic railgun has entered mass production phase, said Song, noting that the heavy demand could come from anywhere since the brushed DC electric motors are widely used in weaponry.

U.S. Intel Says China To Have Railgun-Armed Ships By 2025
A U.S. intelligence review offers new details about a Chinese prototype electromagnetic weapon that first appeared in public earlier in 2018.
BY JOSEPH TREVITHICKJUNE 21, 2018
In January 2018, pictures appeared on social media of the Haiyang Shan, one of the Chinese People’s Liberation Army Navy’s Type 072III-class landing ships, packing an experimental electromagnetic railgun in a huge turret on its bow. Now, the U.S. Intelligence Community reportedly believes this weapon, or one similar to it, will be operational onboard one of China’s warships by 2025.
CNBC was first to report on the U.S. intelligence analysis of the Chinese program on June 21, 2018. In March 2018, China’s state-run media had confirmed that the Haiyang Shan was conducting at-sea tests of the weapon, which had already gone through thousands of tests on land, but offered few specific details about its capabilities. China's interest in electromagnetic weapons dates back at least to the 1980s, but it has been claiming to have made especially significant strides in recent years.
The official U.S. review reportedly says the Chinese electromagnetic cannon can hit targets nearly 125 miles away and fires projectiles at more than seven times the speed of sound. If accurate, this would mean the weapon would be able to strike targets out to its maximum range in a timeframe best measured in seconds.
This is significantly further than the maximum range of any modern naval guns and way faster than even advanced anti-ship and land-attack cruise missiles. It also means that it is capable of lobbing projectiles faster than the U.S. Navy’s own prototype design, which has yet to go to sea.

A low-quality image of the Haiyang Shan, with its experimental railgun under wraps, in January 2018.
It’s the kind of potentially game-changing capability that has made the idea of a practical railgun attractive for navies and ground forces around the world for decades. Chinese ships with these weapons would be able to engage targets across a much broader area, potentially increasing the vectors of attack an enemy force at sea or on land might have to worry about and disrupting their plans.
The ships would also be more flexible and better able to quickly shift their attention to emerging threats and fleeting targets. In theory, electromagnetic guns are especially well suited to that latter category of time-sensitive strikes, since they are so hard to defend against, striking with almost no warning and giving an opponent little chance to move critical assets or evacuate from key sites.
Given the high speed of the projectiles they fire, the weapons could potentially take on other roles in the future, too. The U.S. Navy has envisioned its ships using railguns to shoot down manned and unmanned aircraft and incoming cruise and ballistic missiles.
USN
An official US Navy graphic showing the possible missions for the service's future electromagnetic railguns and traditional weapons firing a similar, hyper-velocity projectile.
According to CNBC’s report, the rounds that the Chinese have been using cost approximately between $25,000 and $50,000 each. This would make them more expensive than standard naval gun shells, but cheaper than projectiles with GPS or other guidance packages that would work in those same weapons. No cannon firing typical ammunition of any kind would be able to match the railgun’s range though and this price point is significantly cheaper than any sub- or supersonic sea-launched cruise missile.
It’s also cheaper than the present price of the Navy’s experimental Hyper Velocity Projectile, or HVP, which has a unit cost of around $86,000. That service, together with the U.S. Army and Marine Corps, is hoping to use this round to get speeds of at least Mach 3 out of existing naval guns and ground-based howitzers. The maximum range of those weapons combined with the new ammunition still wouldn’t be anywhere near that of an actual railgun.
USN
A look at the potential capabilities of the HVP combined with various existing guns compared to the speed and range an actual railgun offers.
The possibility that China will be fielding operational, railgun-armed ships within the next decade could push the Navy to redouble its own efforts to develop an electromagnetic weapon. At present, the service doesn’t expect to conduct its own at sea test until 2019 at the earliest.
“China’s hypersonic weapons development outpaces ours … we’re falling behind,” U.S. Navy Admiral Harry Harris, then head of the top U.S. military command in the Pacific, told members of Congress in February 2018. “We need to continue to pursue that and in a most aggressive way to ensure that we have the capabilities to both defend against China’s hypersonic weapons and to develop our own offensive hypersonic weapons.”
The CNBC report does not say what ship or ships the Chinese plan to install the railgun on operationally. Historically, the limiting factors for railguns have been the immense power they require.
In turn, this requires additional space to house the elaborate electrical infrastructure and the equipment necessary to keep everything, including the weapon itself, cool during sustained firing. The experimental turret on the Haiyang Shan is already significantly bigger than any other large caliber gun mounts in the Chinese fleet.
CHINESE INTERNET
The huge turret housing the prototype railgun on the Haiyang Shan.
The range the railgun offers might allow China to consider deploying it operationally on an amphibious warfare vessel, such as the Type 072III, or even a logistics ship. A striking distance of more than 120 miles could put them out of range of most immediate counterattacks and they could also operate within the safety of a larger surface task force. Of course, The U.S. Navy, among others, is in the process of developing a hypersonic sea-launched anti-ship missile, called Sea Dragon, which would be able to quickly respond to the threat posed by a railgun equipped ship.
If China has truly developed a practical naval railgun, they could look to install additional examples, or derivatives thereof, in land-based mounts, as well. The U.S. Army is similarly developing its own electromagnetic cannon to support ground operations in a way it simply cannot do with traditional artillery and missile systems.
If the Chinese were to deploy these weapons on their various man-made outposts in the South China Sea, it would only further limit the ability of a potential opponent to operate in that region. If the system were at all mobile or air transportable it could be even more flexible in a ground-based role.
Whatever concepts of operation the Chinese might be considering, what is clear is that the country is rapidly expanding both the size and capability of its naval forces. The electromagnetic railgun project is itself tangential to reports of work on an electromagnetic aircraft catapult system that China could install in its next domestically produced aircraft carrier.
On June 20, 2018, new computer generated imagery emerged online that showed a future carrier in a catapult-assisted take-off but arrested recovery (CATOBAR) configuration. China’s two existing aircraft carriers both have a short take-off but arrested recovery (STOBAR) setup that features a large ski jump at the bow.

The expansion of the People’s Liberation Army Navy, or PLAN, goes far beyond flattops, though. China is building surface ships, submarines, and other craft at a prodigious rate. Our own Tyler Rogoway recently examined this build-up, writing:
“The fact that China has been able to realize such a massive expansion of its naval forces, both in terms of quality and quantity, prompts the big question: what will the PLAN look like in another decade?
This haunting concern is one of the largest driving factors behind the U.S. Navy's 355 ship fleet ambitions, which are going to be a major challenge to realize without a dramatic restructuring of its procurement priorities, existing fleet sustainment practices, and facilities management.
“With the Pentagon's shift to 'great power competition' under Secretary Mattis, and with China now America's top technological peer competitor, its ever-strengthening Navy is sure to cast a long shadow on the DoD's list of priorities. But if things continue to go as they are, and with a catapult equipped Chinese aircraft carrier, and possibly a nuclear one as well, on the horizon, the days of America's outright supremacy on and below the high-seas may be coming to an end.”
If the PLAN's fleets actually include any significant number of railgun-equipped ships by 2025, as the U.S. intelligence assessment warns, it is even more likely that the era of near total United States naval supremacy in any prospective conflict, especially in Pacific Region, will have come to a close.

4、突破了磁轨炮用超长水冷轨道的高强异种铜合金搅拌摩擦焊接技术
磁轨炮是利用电磁发射技术的先进装备，采用高强镍铬硅铜/铬锆铜异种合金对接焊而成的超长铜轨道的高性能焊接是其关键。因对接焊两边金属材料强度和特性不同，产热、散热以及组织流动性不一致，对焊头材料及焊接工艺等提出了更高要求。
成功焊接了超长高强镍铬硅铜与铬锆铜合金水冷轨道，水密实验达到7.5MPa(设计要求5.0MPa），为我国磁轨炮研发提供了关键焊接技术支持。

tick tock, tick tock......
目前，由韩珺礼领衔研发的新一代野战火箭呼之欲出，那就是电磁弹射火箭弹武器系统。这个新成果，将我国的火箭优势技术和电磁弹射技术整合起来，实现跨界研究。
韩珺礼是如何“跨界”的呢？事情得从2017年初说起。
彼时，韩珺礼去武汉调研，顺道拜访了被誉为“中国电磁弹射之父”的马伟明院士。
在和马伟明交谈时，韩珺礼突然灵光一闪，问道：“马院士，既然电磁弹射技术能把几十吨重的飞机弹射出去，能否弹射火箭弹？让火箭弹在起飞阶段就获得一个很高的初始速度。”马伟明略作思索回答：“可以试试，应该可以。”
就这样，一个野战火箭发展史上从未有过的设想诞生了。目前，电磁弹射火箭弹已取得重大技术突破，后续发展计划正在一一变成现实。
