Areté proposes the development of Q-switched semiconductor lasers that can be scaled to produce high output peak powers within the blue/green wavelength band. The proposed system will utilize nanostructure quantum wavefunction engineering for gain material designs having extended excited state lifetimes and suppressed non-radiative processes to enable energy storage for high-peak-power optical pu ...

Filamentation of ultra-short laser pulse propagation in non-linear media offers significant potentials allowing to address numerous problems in military and commercial sectors. However, practical implementation of this requires an ability to control the USLP at its propagation through inhomogeneous media, like turbulent atmosphere. On the basis of our approach for combating turbulence effects on p ...

The Candent Technologies “Reduced Cavitation, High Efficiency Outboard Propulsor for Small Planing Craft” Phase II program is structured to develop an advanced waterjet propulsor for the Combat Rubber Raiding Craft (CRRC). This new axial flow waterjet propulsion system is designed as a “bolt on” assembly that replaces the lower unit of the existing MFE 55 outboard motor. This new propulsio ...

We propose development of an improved bottom database suitable for use in the frequency range of 1-10 kHz. Measured transmission loss (TL) and reverberation level (RL) will be jointly processed in building the database. The influence of the rough sea surface, rough seafloor, as well as subbottom heterogeneity will be accounted for during database generation. The rough sea surface will be character ...

The introduction of new systems and technologies is critical for maintaining superiority, yet this brings with it uncertainty regarding the impact on users, teams, and organizations. Rigorous test and evaluation (T&E) practices are essential prior to acquiring and instituting new technologies, particularly to objectively assess the workload imposed on end users. Aptima, Inc. and its partners – S ...

Reducing the violence of Slow Cook-Off (SCO) and Fast Cook-Off (FCO) to acceptable levels is of great interest to the Insensitive Munitions development. For example, the MIL-STD-2105C SCO test for Insensitive Munitions (IM) compliance requires a slow heating rate (3.3°C/hr) until reaction occurs whereby the ensuing reaction is characterized by degree of violence. A Type V (burn) reaction or bette ...

Magnetic materials with high hesitivity values are needed to achieve low-profile conformal broadband magnetodielectric antennas with significantly enhanced efficiency in HF-UHF. The higher the hesitivity, the higher the attainable efficiency in these magnetodielectric antennas. State of the art hesitivity as high as 6×10^6 O/m has been reported in CoZrNb alloy films. Further hesitivity improvemen ...

The Shallow Water and Surf Zone Minehunting program (MAD SWARM) is described that spans the development and demonstration of swarming micro-air vehicles (MAV’s) equipped with Magnetic Anomaly Detectors (MAD’s) to autonomously detect and locate mine targets in shallow water and the surf zone. The MAD Swarm system incorporates low cost micro-air vehicle (MAV) technology, swarming sensor search/c ...

Oceanit proposes to develop and demonstrate novel, tailored, designer separator materials with optimized properties to maximize lithium-ion cell/battery performance, life, safety and reliability.

In Naval, surface electronic warfare (EW), visual displays form critical bridges between warfighters and the complex operational radio-frequency (RF) spectrum they must monitor and interpret. Surface electronic warfare operators and supervisors must monitor and interact with multiple, stove-piped display systems in order to perform their work. Further, the visual displays they employ are not desig ...
