SpaceX launches Air Force’s best GPS yet, ends banner year

By: The Associated Press

CAPE CANAVERAL, Fla. — SpaceX has launched the U.S. Air Force's most powerful GPS satellite ever built.

A Falcon 9 rocket blasted off from Cape Canaveral, Florida, on Sunday, hoisting the satellite toward orbit.

The satellite was supposed to soar Tuesday but rocket concerns and then weather delayed the flight.

Heather Wilson, secretary of the Air Force, says this next-generation GPS satellite is three times more accurate than previous versions and eight times better at anti-jamming. It's the first in a series and nicknamed Vespucci after the 15th-century Italian explorer who calculated Earth's circumference to within 50 miles (80 kilometers).

It was SpaceX's 21st and final launch of the year, a company record.

    US, Poland to Discuss Potential F-35 Sale, Air Force Secretary Says

    BY MARCUS WEISGERBER A U.S. delegation is scheduled to brief Polish defense officials eager to buy the F-35 Joint Strike Fighter later this month, U.S. Air Force Secretary Heather Wilson said Monday. The American team is expected to discuss the costs of buying the Lockheed Martin-made jet as well as the warfighting capabilities it would bring to the Polish military. “They want to deepen their relationship with the United States of America in part by interoperability of advanced equipment,” Wilson said after a Meridian International Center event in Washington. “Those discussions are continuing. We're providing the information that might be needed for them to make a decision.” Poland has been looking to replace its Soviet-era MiG-29 Fulcrum and Su-22 Fitter fighters for several years. Its air force has 31 MiG-29s and and 18 Su-22s, according to the International Institute for Strategic Studies' 2019 Military Balance. In recent weeks, Polish officials said they would buy 32 F-35s. “The Polish government has decided that they want the F-35 and they're in discussions with the United States,” Wilson said Monday. U.S. officials heading to Poland is a sign that the potential deal is going through the standard foreign military sale process. The F-35's design and electronic equipment make it difficult to track for advanced surface-to-air missiles — like the long-range S-300 SAMs that Russia deploys in its Kaliningrad exclave north of Poland. When the U.S. Air Force deployed F-15 fighters from the 104th Fighter Wing to Estonia in 2016, the jets flew close to those Russian surface-to-air missiles. “When you take off [in Estonia] you were either in or very close to being in a Russian [surface-to-air-missile] system out of Kaliningrad,” Col. Tom Bladen, operations officer with the 104th Fighter Wing, told Defense One in October 2016. Earlier this year, the U.S. Marine Corps flew its F-35B jump jets in Syria, where Russia has also deployed the S-300. Last month, the F-35 program director listed Poland as a potential purchaser along with Greece, Singapore, Spain, and Romania. Vice Adm. Mat Winer submitted his written testimony to the House Armed Services tactical air and land forces subcommittee. Later in April, Poland Defense Minister Mariusz Blaszczak told local media that a F-35 deal was “not far away.” While the sale has not been approved by the U.S. State Department, Wilson said it came up when she visited Poland in April. “[T]hey want to be allied with the United States,” the secretary said. “If there's one thing that's really clear, is they fear and detest the Russians.” Wilson touted Warsaw's defense spending, which has been increasing for nearly three decades. Poland is one of seven NATO members who spends above 2 percent of its annual gross domestic product on defense. Buying a fifth-generation fighter is expensive and includes an abundance of training, infrastructure, and maintenance costs beyond the aircraft themselves. Right now, an F-35A, the Air Force version of the Joint Strike Fighter, costs just under $90 million each. For comparison purposes, in January 2018, the Pentagon estimated the sale of 34 F-35s to Belgium at $6.53 billion when all associated costs are factored in. Poland already flies 48 Lockheed-made F-16 fighters. https://www.defenseone.com/business/2019/05/mw-poland-f-35/156971/

    Watch the Defiant helicopter exceed 100 knots

    By: Jen Judson WASHINGTON — The Sikorsky-Boeing SB-1 Defiant coaxial demonstrator flew more than 100 knots in a Jan. 13 flight test as the aircraft — built for the U.S. Army's Joint Multi-Role Technology Demonstrator program — continues to expand its flight envelope in weekly sorties. The aircraft also maneuvered at 30-degree bank turns during the flight in a test of its agility at the Lockheed Martin-owned Sikorsky's Development Flight Test Center in West Palm Beach, Florida. Defiant has been flying for nearly a year. Its first flight was in March 2018 after a delay to the program to challenges mostly related to the manufacturing its rotor blades. The program seems to have picked up the pace. In October, Ken Eland, Boeing's director and manager of its Future Long-Range Assault Aircraft program, told reporters that the aircraft flew three times in March and April, but the company took a pause in flight operations after discovering an issue with the gearbox of the propulsion system test bed, or PSTB, which the team is using for extensive ground tests of the aircraft. Defiant was back up in the air by Sept. 24 when it flew in every direction at speeds of 20 knots. The company said last fall that it planned to push the aircraft to 40 knots and believed it would be able to hit top speeds of 250 knots, which is more than the 230-knot requirement set by the Army. The aircraft is one of two demonstrators flying as part of the Army's Joint Multi-Role Technology Demonstrator, or JMR TD, program, which is meant to inform the service's Future Vertical Lift programs of record, specifically a future long-range assault aircraft the Army wants to field by 2030. The other demonstrator is Bell's V-280 Valor tilt-rotor demonstrator, which as been flying for more than two years and recently completed autonomous test flight series in December. While the official JMR TD phase has ended, according to the Army, both Valor and Defiant continue to fly as each team works to drive down risk related to technology development that would ultimately help a possible program of record move more quickly down the road. Even though the two demonstrators are in different places in their flight test plans, Maj. Gen. Thomas Todd, the program executive officer for Army aviation, said earlier this month that the service wasn't planning to wait for each competitor to reach the same goal posts before proceeding. The only advantage a vendor might have in meeting timelines is that it is able to burn down risk in technology development, he added. The Army is preparing to award an other transaction authority contract to begin a competitive demonstration and risk reduction, or CDRR, effort in March. An OTA is a type of contract that enables rapid prototyping. The CDRR will consist of two phases that last approximately one year each. “In the CDRR, we're really trying to develop a weapons system, not the tech demonstrator,” Brig. Gen. Wally Rugen, who is in charge of the Army's aviation modernization, recently said. “So we're trying to take it to the next level.” https://www.defensenews.com/land/2020/01/17/defiant-exceeds-100-knots
