ARLINGTON, Va. — Boeing has begun work to return the Harpoon cruise missile to operational status in the U.S. Navy's submarine force after a more than 20-year absence.
Boeing received an $10.9 million Naval Sea Systems Command contract late last month to refurbish 16 Harpoon missile capsules and four all-up rounds of encapsulated Block 1C Harpoon missiles for the Navy's submarines. Work is scheduled for completion by December 2022.
The UGM-84A Harpoon Block 1C missiles will be integrated on the Navy's Los Angeles-class submarines. The UGM-84A is encapsulated to be fired from a torpedo tube and has a rocket booster to propel it above the surface of the water and into flight.
“I am happy to report that we will have the first refurbished [Harpoon] missiles delivered to the fleet in [fiscal] ‘21,” said Rear Adm. Thomas Ishee, director of undersea warfare in the Office of the Chief of Naval Operations, speaking Nov. 7 at the Naval Submarine League's annual symposium in Arlington.
In a demonstration in the 2018 Rim of the Pacific exercise, a Harpoon was fired from the Los Angeles-class attack submarine USS Olympia at a target ship, the first time one was fired from a U.S. Navy submarine since the UGM-84A Harpoons were withdrawn from the force in 1997.
The UGM-84A is encapsulated to be fired from a torpedo tube and has a rocket booster to propel it above the surface of the water and into flight.
“The Navy has a deep inventory of Harpoon Block IC missiles,” said Sally Seibert, director, Cruise Missile Systems at Boeing, in a statement. “These missiles can be refurbished and reintegrated into the fleet in a shorter timeframe, and at a fraction of the cost, compared to purchasing new missiles — and that is exactly what our team is doing.”
The Harpoon cruise missile is a combat-proven, all-domain anti-ship missile used by the Navy and more than 30 international customers, a statement from Boeing said. “Evolving over the years to keep pace with emerging threats, the Harpoon Block II includes a GPS-aided guidance system that allows for autonomous, all-weather capability — and can execute both anti-ship and land-strike missions. The more advanced Harpoon Block II+ adds a data link that allows for in-flight targeting updates.”
“The shelf life of the Harpoon missile allows us to maximize existing capability by bringing this weapon back to the submarine fleet,” Seibert said. “Customers who currently have Harpoon missiles in their inventory are prime candidates for refurbishments, or even upgrades, to add this extremely viable and cost-effective weapon to their arsenal.”
Currently, more than 600 ships, 180 submarines, 12 different types of aircraft and several land-based launch vehicles across the world are integrated with Harpoon missiles, Boeing said.

The Air Force can't wait to retire the F-22 Raptor. The future fighter fleet will shrink from seven types to four. See which jets aren't making the cut.

By: Valerie Insinna WASHINGTON — The Air Force on Monday logged another critical technical flaw for the KC-46 tanker, this time revolving around excessive fuel leaks. Under its contract with the service, KC-46 manufacturer Boeing is responsible for paying for a fix to the problem, Air Force spokeswoman Capt. Cara Bousie said in a statement. “The Air Force and Boeing are working together to determine the root cause and implement corrective actions,” she said. “The KC-46 program office continues to monitor the entire KC-46 fleet and is enhancing acceptance testing of the fuel system to identify potential leaks at the factory where they can be repaired prior to delivery.” The problem was first discovered in July 2019, but the Air Force did not say why the issue had been escalated to Category 1 status — the designation given to problems with a significant impact on operations or safety. The service also did not immediately comment on questions about what sort of receiver aircraft were most involved with the deficiency or the severity of the problem. A Boeing spokesman said that the Air Force had discovered 16 aircraft in need of repair, and that seven have already been fixed. “The KC-46 fuel system is equipped with redundant protection for fuel containment. In some cases with this issue, aircraft maintenance crews are finding fuel between the primary and secondary fuel protection barriers within the system,” the company said in a statement. Boeing is working with “utmost urgency” to address the problem and implement a fix to the remaining aircraft, the statement said. A Boeing spokesman added it would take about 10 days to retrofit each aircraft at the rapid response depot facility in San Antonio, Texas. The fix was also being incorporated into production line in Everett, Wash., which is currently undergoing a temporary suspension due to COVID-19. The latest Category 1 deficiency brings the total up to four: The tanker's remote vision system or RVS — the camera system that allows KC-46 boom operators to steer the boom into a receiver aircraft without having to look out a window and use visual cues — provides imagery in certain lighting conditions that appears warped or misleading. Boeing has agreed to pay for potentially extensive hardware and software fixes, but the Air Force believes it will system won't be fully functional until 2023-2024. The Air Force has recorded instances of the boom scraping against the airframe of receiver aircraft. Boeing and the Air Force believe this problem is a symptom of the RVS's acuity problems and will be eliminated once the camera system is fixed. Boeing must redesign the boom to accommodate the A-10, which currently does not generate the thrust necessary to push into the boom for refueling. This problem is a requirements change by the Air Force, which approved Boeing's design in 2016. Last year, Boeing received a $55.5 million contract to begin work on the new boom actuator. Boeing's fixed-priced firm contract for the development of the KC-46 has a $4.9 billion ceiling that leaves the company responsible for any expenses billed in excess of that amount. So far, the company has paid more than $3.5 billion of its own money to fund corrections to ongoing technical issues. https://www.defensenews.com/air/2020/03/31/the-air-forces-kc-46-tanker-has-another-serious-technical-deficiency-and-boeing-is-stuck-paying-for-it/

The communications exercise risk-reduction leading up to a major Army exercise last year took six weeks. Now the lab is able to fulfil that same need in 10 days.
