  David J. Bercuson: Why Japan is building its military, fast

  David J. Bercuson With 18 diesel electric submarines, four so-called “helicopter destroyers” that look suspiciously like small aircraft carriers, 43 destroyers and destroyer escorts, 25 minesweepers and training ships, fleet oilers, submarine rescue ships and other vessels, Japan's navy — the Maritime Self-Defense Force — is the second largest in Asia and one of the largest in the world. It is also highly advanced technologically and is growing all the time. The two 27,000 ton Izumo-class helicopter destroyers, the largest in the fleet, with flat flight decks and islands on the starboard side of the vessels, are small compared to the United States Navy's Nimitz-class aircraft carriers (approximately 100,000 tons) or Britain's new Queen Elizabeth-class carriers (65,000 tons). But if equipped with the new short-take-off-and-vertical-landing F-35B stealth fighter they will still pack a powerful punch. And Japan is considering adding more of these aircraft carriers to its fleet and advanced U.S.-style Aegis class destroyers, capable of shooting down medium-range ballistic missiles. The irony in all of this is that Japan's post Second World War constitution still contains a provision — Article 9 — that prohibits it from possessing any offensive military capability. In the early 1950s, Japan began to build its self-defence forces and now has a powerful navy, a modern medium-sized air force that will soon fly the F-35 along with specially built F-15s, alongside more than 300 fighter aircraft and 50,000 personnel, and a growing land army and marine sea landing capability. Are these military assets “defensive” in nature? Partly, but aircraft carriers, high-speed destroyers, modern fighter aircraft and assault ships are surely as offensive as they are defensive. And Japanese Prime Minister Shinzo Abe has made it plain that in less than two years, he intends to seek to change the Japanese constitution to drastically curtail any obligation Japan has to maintain a purely defensive capability. In other words, he will ask the Japanese people and legislature to bless what Japan has already done. That could be more problematic than people realize. Like Germany, Japan suffered greatly in the Second World War. Virtually all its great cities were levelled either with atomic bombs (Hiroshima and Nagasaki) or fire raids that were carried out by giant B-29 bombers at low altitude at night. The attacks burned the heart out of Japan's cities. In March 1945, 100,000 people were killed in one night in a fire raid on Tokyo and many acres of the city were burned to the ground. Submarine blockades of Japan drastically curtailed food and fuel supplies. Hundreds of thousands of Japanese soldiers were killed either in the United States' march across the Pacific or in the Russian invasion of Manchuria near the end of the war. Japan was a prostrate nation by the end of 1945 and its ancient system of government was a shambles.

  GAO backs use of commercial satellites to host military payloads

  by Sandra Erwin “Using hosted payloads may help facilitate a proliferation of payloads on orbit, making it more difficult for an adversary to defeat a capability." WASHINGTON — The Pentagon should use commercial satellites as host platforms for military sensors and communications packages, says a new Government Accountability Office report released on Monday. GAO auditors investigated the pros and cons of “hosted payloads” and agreed with what private satellite operators have been saying for years: The military can save money and get capabilities on-orbit faster by hitching rides on commercial satellites. The industry has been building huge spacecraft that have extra carrying capacity, and hosting national security payloads is viewed as a profitable business that also helps the military fill a need. The report says there are national security benefits to deploying military payloads on commercial satellites. “Using hosted payloads may also help facilitate a proliferation of payloads on orbit, making it more difficult for an adversary to defeat a capability.” Since 2009, DoD has used three commercially hosted payloads, with three more missions planned or underway through 2022. In 2011, the Air Force created a Hosted Payload Office to provide expertise and other tools to facilitate matching government payloads with commercial hosts. GAO found that defense programs using hosted payloads are not required and generally do not provide cost and technical data, or lessons learned, to the Hosted Payload Office. Having that information would “better position DoD to make informed decisions when considering acquisition approaches for upcoming space system designs.” The Pentagon has not been too keen on hosted payloads for several reasons, GAO noted. There is a perception among some defense officials that matching government payloads to commercial satellites is too difficult. Another concern is that DoD's knowledge on using hosted payloads is “fragmented, in part because programs are not required to share information.” DoD officials who spoke with GAO identified “logistical challenges to matching government payloads with any given commercial host satellite.” For example, they cited size, weight and power constraints as barriers to using hosted payloads. Some individual DoD offices have realized cost and schedule benefits, but “DoD as a whole has limited information on costs and benefits of hosted payloads,” said the report. Officials at the Office of the Secretary of Defense told GAO that “matching requirements between government payloads and commercial satellites is typically too difficult for programs to overcome.” DoD's Hosted Payload Office is “developing tools designed to help address these challenges,” said the report. Defense officials also argued that budget and planning processes are a hurdle. “This can complicate alignment with commercial timelines because the development of a government sensor would need to be underway well in advance of a decision to fund a commercially hosted payload approach.” Officials told GAO that it is possible to align government and commercial timelines. For example, the Missile Defense Agency adopted the commercial host's schedule to ensure its Space Based Kill Assessment payload was ready for integration and launch without delaying the host satellite or missing its ride to space. Similarly, the Defense Advanced Research Projects Agency has been able to align acquisition and development schedules with the commercial host. In its written comments in the report, DoD concurred with GAO's recommendations and noted that the Air Force Space and Missile Systems Center had initiated a major reorganization and that under the new organization, the Hosted Payload Office had changed and may not be the appropriate office for centralizing DoD-wide hosted payload knowledge. Language in the Fiscal Year 2019 National Defense Authorization Act directs the Pentagon to seize oversight of military investments in hosted payloads. https://spacenews.com/gao-backs-use-of-commercial-satellites-to-host-military-payloads/
