OBJECTIVE: Develop a submersible autonomous amphibious breaching vehicle capable of proofing assault lanes from the surf zone (<10 feet depth) through the beach zone, reducing explosive and non-explosive obstacles, and clearing craft landing zones.
DESCRIPTION: The CRAB (Crawling Amphibious Breacher) would be a small, inexpensive, (>$100K per system) submersible autonomous vehicle that will operate in concert with other CRABs. They would be capable of being deployed off-shore, from a depth of approximately 40 feet. CRABs would drop from surface craft to the seafloor and maneuver toward the beach, clearing a lane in a formation. As they move toward the shore, they will neutralize buried and proud (i.e., bottom) sea mines along the way. Mines would be neutralized by targeting the fuze types: pressure fuzed mines by rolling over them; magnetic mines by the heavy metal construction of the CRAB, and tilt-rod fuzed mines by driving into the tilt-rod itself. Once the CRABs exit the surf zone, they will continue up the assault lane, neutralizing land mines by targeting the fuze types, as listed above. CRABs would be small enough that their wreckage can be driven over by an Amphibious Combat Vehicle (ACV) or other large assault vehicles. Once the CRABs reach their limit of advance, they would move out of the assault lane and remain there until the breach is complete. As the CRABs move through the lane, they would drop markers (GPS or other) that landing forces can see on a screen to indicate the cleared lane. These markers would be picked up by receivers in the amphibious force vehicle’s common operating picture systems and generate a visible path on the driver display. The CRAB will not be designed to neutralize moored or floating sea mines and will operate without prior Intelligence, surveillance and reconnaissance (ISR) targeting information. The Marine Corps would like the CRAB to be capable of reducing submerged man-made obstacles using a clamshell type of arm, like that of an excavator, but realizes this may make each CRAB too expensive. This SBIR topic is looking for an innovative way to also reduce man-made obstacles using the most inexpensive means.
Key Performance Parameters (required) of the CRAB:
Key System Attributes (desired) of the CRAB:
PHASE I: Develop concepts for a CRAB vehicle that meets the requirements described above. Demonstrate the feasibility of the concepts in meeting Marine Corps needs and establish that the concepts can be developed into a useful product for the Marine Corps. Establish feasibility by material testing and analytical modeling, as appropriate. Provide a Phase II development plan with performance goals and key technical milestones, and that addresses technical risk reduction.
PHASE II: Develop a scaled prototype for evaluation. Determine the prototype’s capability in meeting the performance goals defined in the Phase II development plan and the Marine Corps requirements for the single amphibious integrated precision augmented-reality navigation system. Demonstrate system performance through prototype evaluation and modeling or analytical methods over the required range of parameters, including numerous deployment cycles. Use evaluation results to refine the prototype into an initial design that meets Marine Corps requirements. Prepare a Phase III development plan to transition the technology to Marine Corps use.
PHASE III DUAL USE APPLICATIONS: Support the Marine Corps in transitioning the technology through test and validation to certify and qualify the system for Marine Corps use. Develop a CRAB vehicle for evaluation to determine its effectiveness in an operationally relevant environment. Support the Marine Corps for test and validation to certify and qualify the system for Marine Corps use.

** TOPIC NOTICE **
The Navy Topic above is an "unofficial" copy from the overall DoD 20.3 SBIR BAA. Please see the official DoD DSIP Topic website at rt.cto.mil/rtl-small-business-resources/sbir-sttr/ for any updates. The DoD issued its 20.3 SBIR BAA on August 25, 2020, which opens to receive proposals on September 25, 2020, and closes October 22, 2020 at 12:00 noon ET.
Direct Contact with Topic Authors: During the pre-release period (August 25 to September 22, 2020) proposing firms have an opportunity to directly contact the Technical Point of Contact (TPOC) to ask technical questions about the specific BAA topic.
Questions should be limited to specific information related to improving the understanding of a particular topic’s requirements. Proposing firms may not ask for advice or guidance on solution approach and you may not submit additional material to the topic author. If information provided during an exchange with the topic author is deemed necessary for proposal preparation, that information will be made available to all parties through SITIS (SBIR/STTR Interactive Topic Information System). After the pre-release period, questions must be asked through the SITIS on-line system as described on the DoD's DSIP website at www.dodsbirsttr.mil/submissions/login.
