The military is building a space plane. Now it looks to have an engine up to the task

By SAMANTHA MASUNAGA

A decade after the U.S. Air Force commissioned the next generation of GPS satellites, the first of these spacecraft is finally set to launch into orbit later this year.

As with other national security missions, a roughly 200-foot-tall rocket will blast the massive satellite to space, fulfilling a contract worth more than $80 million.

But as nations develop technology to disable or shoot down satellites — as China did to one of its own satellites with a ground-based ballistic missile in 2007 — the U.S. military has started to look at options for rapidly and cheaply launching smaller crafts into space.

An experimental program spearheaded by a Pentagon research agency could eventually be part of that solution.

The Defense Advanced Research Projects Agency, along with aerospace giant Boeing Co., is developing a reusable spaceplane expected to launch small satellites 10 times in 10 days.

The vehicle's first test flight is set for 2021, which hints at the Defense Department's growing interest in reusable rocket technology, particularly its potential to drive down launch costs and speed up turnaround time.

In recent weeks, the spaceplane's rocket engine, known as the AR-22, completed 10 test fires in 240 hours without need for refurbishments or major repairs, said Jeff Haynes, program manager at Aerojet Rocketdyne. The test firing took place at NASA Stennis Space Center in Mississippi from June 26 to July 6.

The engine test is “really good progress,” said Claire Leon, director of Loyola Marymount University's graduate program in systems engineering and former director of the launch enterprise directorate at the U.S. Air Force's Space and Missile Systems Center.

“SpaceX has had its success,” she said. “I think this engine test also demonstrates that other companies are doing the technology development and having success that will enable reusability.”

The title of first reusable system belongs to NASA's Space Shuttle, though more recently, several commercial space firms, including Microsoft co-founder Paul Allen's Stratolaunch and British billionaire Richard Branson's Virgin Orbit, have developed systems that would reuse aircraft to launch satellites from the belly of a plane.

    Opinion: How The 2020 Election Is Likely To Affect Defense

    By Byron Callan Unlike in the U.S. health care or energy sectors, it is so far hard to discern much of a stock market reaction for the defense sector in the run-up to the 2020 U.S. election. There has not been the equivalent of issues such as Medicare for all or fracking that has grabbed the attention of defense investors. That might be because defense and security issues have been absent from the debates so far, and Democratic candidates have put forth few detailed defense and foreign policy plans and proposals. It is way too soon to act with conviction on the potential outcomes of the 2020 election and their implications for defense. Polls can and will change. The likely Democratic presidential candidate may not be known until April, when most of the primaries are completed, or July 2020, when the party holds its convention. And it remains to be seen how that candidate will fare against President Donald Trump, presuming he is not removed from office. Still, leaders at defense companies and analysts have to assess potential outcomes and what they may entail for 2021 and beyond. The current consensus is that there likely will be split-party control of Congress and the White House in 2021-22. The House probably will remain in Democratic control, but the Republicans may retain a slim majority in the Senate, given the number of “safe” seats they will defend. Democrats might sweep in, but they are very unlikely to gain a 60-seat majority, and it is arguable that if they do not, the chamber will vote to do away with cloture, which gives the minority party in the Senate power to shape and channel legislation. This alone should temper expectations that there will be radical changes for defense. Moreover, the day after the 2020 election, both parties will have their eyes on the 2022 election, when 12 Democratic and 22 Republican seats will be contested. If Trump is reelected, the simplest path forward will be to conclude that current defense policies will remain in place. Congress has not been willing to approve the deep nondefense discretionary cuts the administration has proposed for 2017-19, and it is not clear what would change this posture in 2021-22. Barring a major change in the global security outlook, U.S. defense spending may thus remain hemmed in by debt/deficit concerns and demands for parity in increases of nondefense spending. Trump is likely to continue to browbeat allies in Europe and Asia to spend more on defense. The Pentagon will push ahead with its current major modernization and technology priorities, including artificial intelligence, directed energy and hypersonics, and there should be some continuity with civilian leadership at the Pentagon. However, the global security outlook may be the biggest variable for the sector to assess. Iran has not shown any readiness to bow to U.S. “maximum pressure,” and North Korea has not denuclearized. How Russia and China respond to the prospects of another four years of Trump also has to be weighed. NATO and other alliances also may be under more stress. And inevitably, there are likely to be new security issues in the early 2020s that are not top of mind or even conceivable today. There are a range of defense views and perspectives among the leading Democratic candidates. The views of the two most progressive candidates—Sen. Bernie Sanders (I-Vt.) and Sen. Elizabeth Warren (D-Mass.)—could be viewed as potentially the most disruptive for defense. Warren, in particular, has emphasized her view of “agency capture” by major U.S. contractors, and her health care plan is to be paid for in part by a $798 billion cut to defense spending over 10 years, though the baseline of those cuts has not been stipulated. If a progressive candidate appears to do well in the Democratic nomination process and in polling against Trump, however, it will be useful to recall the congressional dynamic noted above. Congress could act as a firewall against steeper cuts and sweeping change. Equally, it is useful to recall that what candidates promise is not always what they do once they are in office. A more moderate, centrist Democratic candidate such as former Vice President Joe Biden or South Bend, Illinois, Mayor Pete Buttigieg may appear benign for defense and will very likely face the same geopolitical security challenges that Trump could face. If there is a shift back toward a U.S. promotion of democracy and human rights, that could affect recent international defense export patterns and raise tensions with China, Russia and other autocratic regimes. Probably, there will be a bigger debate over nuclear strategic forces modernization, the role of technology in defense and whether it can deliver credible military capability and deterrence at lower cost. Even if U.S. defense spending evidences little real growth in the early 2020s, these factors could be the most important for contractors to navigate. https://aviationweek.com/defense/opinion-how-2020-election-likely-affect-defense
