DARPA occasionally stands up temporary special projects offices focused on coordinating, developing and/or deploying advanced capabilities on an accelerated time scale. These efforts fall outside of DARPA’s typical program structure and leverage the Agency’s unique organization and skill sets to make rapid progress in technology areas that are critical to national security. DARPA currently operates one special projects office: the Aerospace Projects Office (APO).

The Tactical Technology Office is holding a Proposers Day meeting to provide information to potential proposers on the objectives of the new Manta Ray program and to facilitate teaming. The principal objective of Manta Ray is to open a design space for future unmanned underwater vehicles (UUVs) that are capable of both long duration missions and large payload capacity. A secondary goal of the program is to advance key technologies that will benefit other naval designs such as low lifecycle cost UUV operations, long duration undersea energy management techniques, biofouling reduction technologies, and long duration navigational enablers.
The Cross-Domain Maritime Surveillance and Targeting (CDMaST) program seeks to identify and implement architectures consisting of novel combinations of manned and unmanned systems to deny ocean environments to adversaries as a means of projecting power. By exploiting promising new developments in unmanned systems along with emerging long-range weapon systems, the program aims to develop an advanced, integrated undersea and above-sea warfighting capability able to execute long-range attacks against submarines and ships over large contested maritime areas.
Military platforms and structures, such as vehicles, ships, aircraft and buildings, must withstand transient shock, vibrations and other structural loads in a variety of demanding operational environments. These frequent and varying transient loads are often transmitted to occupants, which can degrade warfighters’ performance by creating discomfort and injuries. In addition, varying loads can lead to shortened service life for the military platforms, as well as the equipment inside. Currently, structures designed to achieve high stiffness for static loads (dead weight) typically can’t adapt to or dampen dynamic loads well. Conversely, structures designed for high damping do not carry conventional loads as efficiently.
