Stiletto Stealth Ships: Look Different. Ride Different. Buy Different

Stiletto Stealth Ships: Look Different. Ride Different. Buy Different 30-Jul-2008: M-Ship Stiletto The late Vice-Admiral Cebrowski’s legacy at the Pentagon’s Office of Force Transformation. With the formal roll-out of the 88-foot Stiletto stealth ship and its cutting-edge “M-Hull” wave-damping design, that legacy takes another step forward. The Stiletto is part of Project WolfPac, which aims to test new concepts of shallow-water and riverine warfare organized around swarms of smaller, affordable ships linked by communications. The Stiletto can slip into shallow waters, launching inflatable boats and even UAVs while serving as a communications hub via its “electronic keel.” Best of all, the M-Hull significantly reduces the pounding its occupants take from waves – poundings that often result in back injuries that cut careers short, or leave sailors with lingering disabilities in later life. After a long, drawn-out testing period, the ship is finally being given a chance to silence doubts about its ability to stand up to open sea conditions. It has been deployed – with a crew of Army mariners to operate it… The Stiletto Program Contracts and Key Events Appendix A: M-Hull Technology – From Venice to Victory Appendix B: Additional Readings The Stiletto Program Rear w. inflatables well Stiletto program manager US Navy Commander Greg Glaros’ entry in the DefenseTech.org comments section provided the best window into the thinking behind Stiletto, whose technology may migrate to other platforms as well: “Stiletto was constructed in 15 months starting Oct 04. She is made completely out of Carbon fiber. Her purpose is to insert emerging technology at little cost due to her Electronic Keel and to provide a venue for operational experimentation. It is not perfect, nor is she designed to solve everyone’s needs (no she does not submerge – we left that to the Billion $ club). What she is designed to do is expand our technical competence against an elusive adversary and learn operationally in a very short period of time. With regards to its survivability or operational relevancy we will all learn by her mere existence. Easy to kill??? – We seem to easily lose sight that most military systems are all easy to destroy by a willing enemy. Stiletto & ScanEagle launcher Our objectives should be focused on matching our adversaries at scale with an ability to cope and adapt – surely the Stark, Cole, M-1 ABRAMS, and Hummers have taught us how easy it is to kill systems designed to survive everything our engineering imagined – unfortunately what our engineer imagine often do not align with what our enemy intends… During the last two weeks Stiletto out performed our expectations – with advanced speeds in calm waters and not so calm…and out performing in other areas in a time frame and within a cost that seems to be out of the reach of our requirements procss and acquisition system. Time to operational market matters…” The Stiletto will cost about $6 million to build, while the overall costs of the experiment are expected to reach about $12 million. DefenseTech’s main coverage of the Stiletto ship is a good article with a number of valuable links, but the key issue for the ship will be its composite hull’s ability to stand up to the sea’s inevitable pounding. Contracts and Key Events June 30/08: Stiletto makes a refueling stop at the American territory of Guantanamo Bay, Cuba. The ship has been moved to NAVSOUTH’s area of responsibility, where it will support the Coast Guard’s efforts and participate in anti-drug operations around the Caribbean. The ship is actually operated by a small crew of Army mariners from the 7th Sustainment Brigade of the 10th Mountain Division. They can also deploy a rigid hull inflatable boat (RHIB) with 7 fully armed Coast Guardsmen from the ship, in order to conduct ground operations. July 2008: A National Defense Magazine article says that Stiletto has been in use as a test bed ship, courtesy of the Pentagon’s rapid reaction technology office. The office inherited the ship when the Office for Force Transformation was disbanded, and needed a maritime test bed for the concepts companies brought to it. Since Stiletto was designed from the outset to accept new technologies quickly and easily, it was a natural fit. May 9/06: M Ship Co. announces that the U.S. Navy’s Office of Naval Research has awarded the firm a $750,000 contract, including options, to validate the potential of the innovative M-hull technology. The Navy Small Business Innovation Research (SBIR) contract calls for tank testing and sea trials for the M-hull technology, and the development of computational fluid dynamics (CFD) tools for quantifying the hull’s performance. This seems arcane, but it’s vital if one wishes to model the hull’s performance in a variety of sea conditions. Existing ship hull designs have undergone extensive modeling, as well as real life use, allowing certification agencies to declare them safe within a certain range of conditions. New hull technologies need this, too, but the cost burden for the inventor can be crushing without funding like this. Jan 31/06: M Ship Co. announces the launch of the M80 Stiletto, designed as an operational experiment for the Pentagon’s Office of Force Transformation (OFT). The vessel combines carbon fiber construction with a networked architecture and a revolutionary M-hull. The release also discusses Cebrowski’s legacy. Appendix A: M-Hull Technology – From Venice to Victory Interestingly, the M-hull evolved from a challenge to help solve the serious problem of wave erosion to the ancient buildings of Venice, Italy. Since the streets of this city are water, the authorities were faced with the unique problem of reducing waves created by motorboats to protect the foundations of the buildings along the canals. Chuck Robinson, who lives in the USA but has an apartment in Venice, decided that he had to do something. The result of this effort was the M-hull. This patented hull form exhibits the shock mitigation features of the deep-V hull with the roll stability of a multihull. In addition, the hull form creates a natural surface effect that not only enhances top speed performance, but actually uses the bow wave energy to reduce the overall wake signature. Current M-Hull products include water taxis, the EcoBarca environmentally sensitive tourism ship, and a sport fishing vessel in addition to the Stiletto. Other proposed variants include cargo, commercial shipping, Coast Guard, and larger military applications like the MS 120 and MS 200 Littoral. Perhaps the most interesting potential for the M-Hull, however, may lie in its promise as a component of seabasing. As this M-Ship Co. press release notes, its co-founder Bill Burns says: “I think there could be some opportunity for seabasing using the M-hull technologies, not only for the connectors but also for the seabase itself,” he said. “And we are developing some conceptual designs where we can actually build square ships that can link together and break apart based on the mission needs.”
