    Pentagon seeks to classify future year defense spending plans

    By: Aaron Mehta WASHINGTON — The Pentagon has asked Congress to allow it to classify its Future Year Defense Program spending projections, new documents have revealed. The FYDP numbers, which project five years into the future, are considered essential information for the public to see where the Department of Defense expects to invest in the future, and to hold the department accountable when those spending plans change. Information on the request was published Monday by Steven Aftergood of the Federation of American Scientists. Aftergood wrote that the proposal would “make it even harder for Congress and the public to refocus and reconstruct the defense budget.” In its request to Congress, the Pentagon wrote that an unclassified FYDP “might inadvertently reveal sensitive information,” despite the fact the numbers have been unclassified since 1989. “With the ready availability of data mining tools and techniques, and the large volume of data on the Department's operations and resources already available in the public domain, additional unclassified FYDP data, if it were released, potentially allows adversaries to derive sensitive information by compilation about the Department's weapons development, force structure, and strategic plans,” the DoD wrote. It added that there is a commercial concern with the FYDP providing too much information to industry. “The Department is also concerned about the potential harm to its interactions with commercial interests by release of FYDP information prior to the budget year. Exposing resources allocated to future acquisition plans may encourage bids and other development activities not beneficial to the Government,” the proposal read. Seamus Daniels, a budget analyst with the Center for Strategic and International Studies, said in a tweet that “DoD's proposal to eliminate the unclassified FYDP severely limits the public's ability to track how strategy aligns with budgets and how program plans change over time. Serious step backwards in transparency from the department.” Earlier this year, the No. 2 uniformed officer in the Pentagon railed against the department's tendency toward overclassification, calling it “unbelievably ridiculous.” The Pentagon has requested a number of legislative changes this year, in addition to the FYDP classification attempt. Among the notable requests are one that would remove the requirement for the defense secretary to “notify the Senate and House Armed Services Committees whenever the Secretary establishes or modifies an end-of-quarter strength level;” a request for the ability to add an additional 15 general officer billets in the combatant commands and three general officer billets on the Joint Staff, to be filled exclusively by reserve component officers; and a request to rename the assistant secretary of defense for special operations and low-intensity conflict as the assistant secretary of defense for “Special Operations and Irregular Warfare.” https://www.defensenews.com/pentagon/2020/03/30/pentagon-seeks-to-classify-future-year-defense-spending-plans/

    New undersea drones are smaller, cheaper and can be refueled deep under water

    By: Victoria Leoni NATIONAL HARBOR, Md. — Bright yellow underwater drones were a visible highlight on the exhibition floor here at the Sea-Air-Space Exposition. Among the autonomous underwater vehicles (AUVs) featured: a new high-speed, micro-sized vehicle by Hydroid and a subsea drone refueling station by Teledyne Energy. Hydroid's Remus M3V is substantially smaller than previous models. With a compact, A-size (36-inch long, 4.875-inch diameter) envelope and no fins or appendages, the vehicle can achieve speeds of more than 10 knots and dive up to 300 meters. It can be used in search and survey; intelligence, surveillance and reconnaissance (ISR); and multivehicle missions. With its variable center of gravity, the Remus M3V can also operate in buoy mode. Its key marketing points are its small size, low cost and compatibility with existing AUV operating systems. “The Navy always wants more with less,” said Justin S. Reid, business development manager at Hydroid. “They want a smaller vehicle that can do the same things as a larger vehicle, and also the price point to match it.” Teledyne Energy featured its untethered subsea power station at the exposition, along with its Gavia AUV. The Gavia can perform side-scan sonar operations to capture images of the sea floor. It is intended to travel ahead of Navy fleets and transmit oceanographic data back to the vessels. Teledyne's subsea power station can remotely refuel the Gavia and other underwater vehicles. Deployable via ship or helicopter, the fuel cell system has an energy storage of 200 kilowatt-hours and an operating depth of 3,000 meters. Teledyne will demonstrate the subsea power station at the Navy's Advanced Naval Technology Exercise in August.
