Raytheon exits precision strike missile competition (25. März 2020)
In what was described as a mutual decision, Raytheon is exiting from the Army’s Precision Strike Missile technology maturation and risk reduction phase without a flight test under its belt, according to a company statement sent to Defense News on March 25.

“Although we remain confident in our resolution to the technical issue that delayed our DeepStrike flight test, the Army and Raytheon have mutually come to the decision to conclude our participation in the PrSM Technology Maturation and Risk Reduction phase,” the statement reads in full.
“The decision was made to not provide additional money to Raytheon to help them try to meet the requirements to get into the next phase of the competition and, really, that meant have a successful flight test,” Brig. Gen. John Rafferty, who is in charge of Army Long-Range Precision Fires modernization, told Defense News in a March 25 interview.

“Their period of performance ended on the 20th, last Friday, and so they dropped out of the competition because they didn’t meet the requirement for the next phase,” he said. “It has been a competitive program and all competitions end and this one ended in this way.”

Lockheed now has two successful test flights of its PrSM offering, but Raytheon had struggled with a technical issue since late last year when it was scheduled to execute its first test flight at White Sands Missile Range, New Mexico.

The company’s next flight test will be held April 30th, Rafferty said.
While Raytheon may be out now, Rafferty said, “I think it’s important to remember that we view not just the base missile as the competitive part of PrSM.”

The Army intends to spiral in capability to the base missile later on. Spiral one adds a more capable seeker, and spiral two would enhance lethality of the weapon either through sub-munitions or “a couple of alternatives that we are considering for that," Rafferty said.

And the service plans to extend the range of the PrSM missile so there are opportunities for competition there “and we would welcome Raytheon as an important competitor,” Rafferty said, adding Raytheon’s design features a compelling propulsion system, which fundamentally differs from Lockheed’s design and could be considered down the road.
But the Army believes the baseline missile could actually reach a range of 550 kilometers based on data from both Raytheon and Lockheed. The Army has said it wouldn’t consider adjusting its requirements until each company has had a chance to see how their respective missile behaves in real flight tests.

Lockheed’s third flight will test the missile’s performance at an even shorter range. The company is waiting on a potential award to conduct three more flights tests in a second phase of the program. Those tests will include a maximum range test as well as a salvo firing of two missiles.

Trump administration discussed conducting first U.S. nuclear test in decades
By
John Hudson and
Paul Sonne


May 23, 2020 at 3:32 a.m. GMT+2

The Trump administration has discussed whether to conduct the first U.S. nuclear test explosion since 1992 in a move that would have far-reaching consequences for relations with other nuclear powers and reverse a decades-long moratorium on such actions, said a senior administration official and two former officials familiar with the deliberations.

The matter came up at a meeting of senior officials representing the top national security agencies May 15, following accusations from administration officials that Russia and China are conducting low-yield nuclear tests — an assertion that has not been substantiated by publicly available evidence and that both countries have denied.

A senior administration official, who like others spoke on the condition of anonymity to describe the sensitive nuclear discussions, said that demonstrating to Moscow and Beijing that the United States could “rapid test” could prove useful from a negotiating standpoint as Washington seeks a trilateral deal to regulate the arsenals of the biggest nuclear powers.

The meeting did not conclude with any agreement to conduct a test, but a senior administration official said the proposal is “very much an ongoing conversation.” Another person familiar with the meeting, however, said a decision was ultimately made to take other measures in response to threats posed by Russia and China and avoid a resumption of testing.

The National Security Council declined to comment.

During the meeting, serious disagreements emerged over the idea, in particular from the National Nuclear Security Administration, according to two people familiar with the discussions. The NNSA, an agency that ensures the safety of the nation’s stockpile of nuclear weapons, didn’t respond to a request for comment.

The United States has not conducted a nuclear test explosion since September 1992, and nuclear nonproliferation advocates warned that doing so now could have destabilizing consequences.

“It would be an invitation for other nuclear-armed countries to follow suit,” said Daryl Kimball, executive director of the Arms Control Association. “It would be the starting gun to an unprecedented nuclear arms race. You would also disrupt the negotiations with North Korean leader Kim Jong Un, who may no longer feel compelled to honor his moratorium on nuclear testing.”
President Barack Obama supported the ratification of the CTBT in 2009 but never realized his goal. The Trump administration said it would not seek ratification in its 2018 Nuclear Posture Review.

Still, the major nuclear powers abide by its core prohibition on testing. But the United States in recent months has alleged that Russia and China have violated the “zero yield” standard with extremely low-yield or underground tests, not the type of many-kiloton yield tests with mushroom clouds associated with the Cold War. Russia and China deny the allegation.
Every year, top U.S. officials, including the heads of the national nuclear labs and the commander of U.S. Strategic Command, must certify the safety and reliability of the stockpile without testing. The Trump administration has said that, unlike Russia and China, it isn’t pursuing new nuclear weapons but reserves the right to do so if the two countries refuse to negotiate on their programs.
The primary remaining pillar of the arms-control framework between the United States and Russia is the New START pact, which places limits on strategic nuclear platforms.

The Trump administration has been pushing to negotiate a follow-on agreement that includes China in addition to Russia, but China has rejected calls for talks so far.

Trump’s presidential envoy for arms control, Marshall Billingslea, warned that China is the “midst” of a major buildup of its nuclear arsenal and “intent on building up its nuclear forces and using those forces to try to intimidate the United States and our friends and allies.”

One U.S. official said a nuclear test could help pressure the Chinese into joining a trilateral agreement with the United States and Russia, but some nonproliferation advocates say such a move is risky.

Text of a Letter to Certain Congressional Committees on the United States Strategic Approach to the People’s Republic of China

https://www.whitehouse.gov/briefings-st ... lic-china/


United States Strategic Approach to The People's Republic of China
To respond to Beijing’s challenge, the Administration has adopted a competitive approach to the PRC, based on a clear-eyed assessment of the CCP’s intentions and actions, a reappraisal of the United States’ many strategic advantages and shortfalls, and a tolerance of greater bilateral friction. Our approach is not premised on determining a particular end state for China. Rather, our goal is to protect United States vital national interests, as articulated in the four pillars of the 2017 National Security Strategy of the United States of America (NSS). We aim to: (1) protect the American people, homeland, and way of life; (2) promote American prosperity; (3) preserve peace through strength; and (4) advance American influence.
3. Preserve Peace through Strength

The 2018 National Defense Strategy (NDS) prioritizes long-term competition with China and emphasizes modernization and partnerships to counter the PLA’s technological advancements, force development, and growing international presence and assertiveness. As described in the Nuclear Posture Review, the Administration is prioritizing the modernization of the nuclear triad, including the development of supplementary capabilities designed to deter Beijing from using its weapons of mass destruction or conducting other strategic attacks. Meanwhile, the United States continues to urge China’s leaders to come to the table and begin arms control and strategic risk reduction discussions as a nuclear power with a modern and growing nuclear arsenal and the world’s largest collection of intermediate range delivery systems. The United States believes it is in the interest of all nations to improve Beijing’s transparency, prevent miscalculations, and avoid costly arms buildups.

The Department of Defense is moving quickly to deploy hypersonic platforms, increasing investments in cyber and space capabilities, and developing more lethal fires based on resilient, adaptive, and cost-effective platforms. Together, these capabilities are intended to deter and counter Beijing’s growing ambitions and the PLA’s drive toward technological parity and superiority.

Live nuclear testing could resume in ‘months’ if needed, official says
A live nuclear test could be arranged within “months” if requested by the president, a top defense department nuclear official said Tuesday, following a report that the Trump administration has discussed the first American nuclear test in decades.

However, Drew Walter, performing the duties of deputy assistant secretary of defense for nuclear matters, stressed that there “has been no policy change” when it comes to avoiding live nuclear testing.
Walter said it was his understanding that “a very quick test with limited diagnostics” could occur “within months” if ordered by the president for technical or geopolitical reasons. "I think it would happen relatively rapidly.”

However, the data gathered from such a test would likely be minimal, given the need to quickly set it up; a fuller test, to gather large amounts of useful data, might be more likely to take years, he said at an event hosted by the Mitchell Institute.

Under presidential guidance going back to 1993, NNSA is required to maintain a capability to conduct a nuclear test within 24 to 36 months, according to an agency document. However, “Nuclear test response time depends on the specific details of the test.”

Walter added that he believes the NNSA has a spot picked out in Nevada where it could do underground testing.
Walter hinted in that direction Tuesday, saying there is “widespread concern about the major disparity in the way Russia and China appear to interpret and adhere” to the CTBT guidelines. He added that the U.S. “should be mindful of the implications over the long term of what other countries will learn, maybe not today but in the long term, if they conduct” live nuclear tests.
