    Darpa’s new missile hints at truly game-changing technology

    It isn't the warhead, its the engine. Rotation Detonation Engines.

    It will be applied to non-nuclear naval vessels and aircraft. Hello range problem and Chinese A2/AD.


    DARPA’S NEW MISSILE HINTS AT TRULY GAME-CHANGING TECHNOLOGY

    Last week, the Defense Advanced Research Projects Agency (DARPA) quietly unveiled a new high-speed missile program called Gambit. The program is meant to leverage a novel method of propulsion that could have far-reaching implications not just in terms of weapons development, but for high-speed aircraft and even in how the Navy’s warships are powered.









    This propulsion system, known as a rotation detonation engine (RDE), has the potential to be lighter than existing jet engines while offering a significant boost in power output, range, and fuel efficiency.


    The Gambit missile is just one of a number of programs placing a renewed focus on RDE technology, though for the most part, these systems have managed to fly under the media’s radar. That is, except for Aviation Week & Space Technology Defense Editor Steve Trimble, who has covered these recent developments at length. Trimble was kind enough to discuss that work with me as I sought to better understand just how big a deal this technology could be.


    Rotation Detonation Engines may not be common in discussion today, but amid the ongoing hypersonic arms race and America’s renewed focus on deterring near-peers, this technology could help offset a number of tactical and strategic advantages presented by America’s opponents in places like Europe and the Pacific…


    …And it may be closer than you think.

    ***


    Rotating detonation engines have been the subject of theory and speculation for decades, but have yet to cross the barrier between theory and practical application.


    In theory, a rotating detonation engine promises to be much more efficient than traditional jet engines, potentially providing missile applications a serious boost in range and speed. That could also mean fielding smaller weapons capable of achieving the same speeds and ranges as today’s missiles.


    In aircraft applications like jet fighters, rotation detonation engines could offer similar benefits to missiles in terms of range and speed, while potentially reducing maintenance requirements. Fighters, in particular, rely on afterburners, which effectively firehose fuel into the engine’s exhaust stream for added thrust, which, you can imagine, rapidly depletes fuel stores and reduces the fighter’s range. RDEs could potentially allow for a similar boost in thrust with a dramatically reduced fuel penalty.


    But where this technology could be the most useful is in powering the Navy’s future non-nuclear surface vessels, providing increased power production, range, and speed while having a seriously beneficial impact on the Navy’s budgetary bottom line.

    Cool. That could make a difference in a decade or two.
    Call your state legislators and insist they approve the Article V convention of States to propose amendments.

    I don't know about the timeline, but considering it is still at DARPA that may be accurate. I say, good. Keep working on the next tech.

    Typically from DARPA to Big Military is about two decades. There have been exceptions.

    So no rotating fans or compressors? I assume the fuel pumps must be high pressure for the injectors.
    Let's go Brandon !!!
