Direct-to-Phase II F2-WARS Sonobuoy

Amount: $923,043 Topic: N242-D09

The current capabilities of mid-frequency transmitter/receiver acoustic sensors do not provide calibrated coherent source/receiver combinations tailored for environmental characterization or advanced passive processing. The Navy requires innovative sensor technologies with enhanced electromechanical property ceramics that fill frequency, bandwidth, and responsiveness gaps for the transmitter and receiver elements that are capable of transmitting, collecting, and processingsurveillance information. Enhanced signal processing techniques for both active and passive processing can enable improvements in capabilities at the F2 Mid Frequency.SLA will develop and demonstrate an F2-WARS sonobuoy prototype. It will take the form of a source and receiver combination prototype system that can characterize the acoustic ocean environment in the F2 Mid-Frequency range and will build upon previous successful designs.The system will consist of an acoustic projector array, acoustic receive array, a lower unit, and a surface unit. The lower unit will provide battery power and a power amplifier for powering the projector array. It also collects and aggregates data from the receive array to send to the surface unit. The surface unit will accept commands from and transmit data to the sonobuoy receiver radio and the acoustic processor platform over an RF link per the NATO STANAG 4718 standard.The design will build upon the DDVLA sonobuoy that SLA has developed and tested. It is now in Phase III low-rate initial production. DDVLA is a receive-only sonobuoy that operates at the F7 frequency. The DDVLA receive elements will be leveraged for this Phase II prototype program. They will be modified for the F2 frequency, but their low-noise performance, high-resolution data acquisition, and signal processing algorithms will transfer to this program. The DDVLA surface unit with a NATO STANAG 4718 compliant radio will be used as-is for this Phase II prototype.

Mid-Frequency Active Sonobuoy Development

Amount: $999,999 Topic: N161-001

The proliferation of ever quieter submarines, combined with the challenging acoustic characteristics of littoral waters, create a significant challenge for incumbent Anti-Submarine Warfare (ASW) platforms. The interoperability of these platforms to conduct ASW is a challenge the U.S. Navy is addressing through this topic by supporting the development of an integrated ASW capability which would leverage multi-static acoustic operations from what have traditionally been mono-static platforms. Our SBIR Phase II effort achieved the build of a NATO A-size prototype which met many program objectives. For this follow-on Phase II project, development will continue on elements which are critical for certification of a production sonobuoy capable of meeting the objectives of the original MFAS solicitation.

Expanding Mission Capability of ADARO Small Unmanned Surface Vessel (USV) through Innovative Cost Reduction Methodologies

Amount: $74,959 Topic: N234-P05

The ADARO platform is a small unmanned surface vessel (USV) which provides a modular payload capability, extended range, and system interoperability that are exceptional for its class. ADAROÆs ability to deliver a variety of highly capable payloads downrange with low observability provides a unique mission capability in the small USV market. Despite the unique capability of the craft, its high overall system cost has limited broad Department of Navy (DON) adoption. SeaLandAire Technologies, Inc. (SLA) proposes to decrease overall cost of the ADARO system through improvements in production scale, product design, and manufacturing processes. Specific innovations to ADARO will include application of design for manufacturing and assembly (DFMA) and lean manufacturing principles. These innovations will enable SLA to transition ADARO from a craft optimized for rapid iteration and low cost of development to one optimized for low cost of production and sustainment. By investing in cost reduction of the core ADARO craft, this proposal seeks to reduce the mission cost for all ADARO CONOPs and enable higher-capacity, lower-cost applications, such as swarming and expendable missions. This improvement will allow the DON to utilize ADARO with increased capacity as a covert platform to support ISR, SIGINT, EW, and kinetic missions, thereby asserting dominance in contested littoral environments.

Miniaturized High Data Rate Sonobuoy Tether

Amount: $991,320 Topic: N221-023

SeaLandAire (SLA) will build on the work done in the Phase I effort to address the NavyÆs need for a strengthened, full-duplex communications datalink between the surface unit of a sonobuoy and its suspended payload, as described in Navy SBIR Topic N221-023. SLA, along with our partner AFFOA, will develop, build and test prototype tethers. ĀWe will design a fiber optic based tether which will act both as a strength member to support the suspended payload and as a high data rate communication pathway between the payload and the upper unit of the sonobuoy, and develop innovations with respect to existing challenges in buoy operational life / mean time between failure, unit production cost, and tensile strength.Ā We will work with the manufacturer to develop and revise the materials and their fabrication processes, as required, to produce prototype quantities of the FO tether toward an eventual low cost product.Ā The prototype tethers will be evaluated in the lab, freshwater, and the ocean to measure performance against metrics and provide feedback for improvement to meet specifications.Ā We will develop and fabricate sonobuoy subassemblies and an A-size sonobuoy configuration that will be used to evaluate the FO tether in the relevant ocean environment.Ā This will include winding the tether into deployable packs, and transmitting representative data through the tether.

PHASE Ph. II.5

Amount: $1,410,600 Topic: N08-023

Commander, Patrol and Reconnaissance Group (CPRG) has prioritized the PHASE technology insertion into the SSQ-53 and SSQ-62 production sonobuoys and has recommended an operational flight demonstration. PHASE performance to date, has been credible. The PHASE flight kit technology consists of a unique single parachute that is drag-based and a three-stage air decent system. This PHASE technology enables the P-8A to conduct ASW operations at higher than traditional altitudes. Cost savings are negligible, but operational capabilities are improved when deploying PHASE sonobuoys in Global Positioning System (GPS) denied environments. The primary benefit of deploying the SSQ-53 and SSQ-62 PHASE modified sonobuoys include more precise sonobuoy placement and improved time-to-fall during P-8A ASW operations during critical target localization, track, and attack kill chain phases. Other attributes include 1) potential cost avoidance in fuel costs by operating the P-8A at more efficient operational altitudes; and 2) the P-8A performing ASW operations at higher altitudes may result in less platform fatigue. In October 2019, SeaLandAire delivered 50 SSQ-62 and 14 SSQ-53 integrated PHASE flight kits in support of a government airdrop test from a P-8A. This airdrop test was successfully completed in November 2019, by VX-20 with VX-1 personnel observing. VX-20 airdropped a total of 39 SSQ-62 and 6 SSQ-53 with the PHASE flight kits from 15,000ft. In summary, the test met its objectives with all PHASE sonobuoys successfully surfacing, 5 of 6 SSQ-53 PHASE sonobuoys and 33 of the 38 SSQ-62 sonobuoys were fully operational after the buoy surfaced. The average time of fall for the PHASE modified SSQ-53 was 86.6 seconds and the SSQ-62 had an average time of fall of 67.1 seconds. The PHASE modified SSQ-62 had an average time of fall 55.4 seconds faster than the production buoy and the SSQ-53 PHASE modified buoy was 71.8 seconds faster than its production counterpart. The primary goal for this Phase II.5 effort is to mature the PHASE design and provide sufficient PHASE-modified sonobuoys to support in-flight assessments of PHASE effectiveness in an operationally relevant ASW environment. Additionally, the PHASE technology will be subject to cost and qualification assessments to improve production-readiness in transition to an ECP.

Miniaturized Sonobuoy High-Data-Rate Tether

Amount: $239,705 Topic: N221-023

SLA plans to address the Navy’s need for a strengthened, full-duplex communications datalink between the surface unit of a sonobuoy and its suspended payload, as described in Navy SBIR Topic N221-023. SLA and AFFOA will partner to understand the problem posed in the Topic, to develop a notional approach to design a fiber which will act both as a strength member to support the suspended payload and as a communication pathway between the payload and the upper unit of the sonobuoy, and to develop innovations with respect to existing challenges in buoy operational life / mean time between failure, unit production cost, and tensile strength, including exploring new inner diameter pack form factors, which will incorporate smaller subsystems thus pushing the fiber wrap outward and enlarging the fiber innermost wrap diameter, exploring potential lower-cost raw materials and potential dual-use materials to minimize the BOM and processing steps, and exploring dual-battery pack technologies and wake up methodologies.

High Gain Array of Velocity Sensors

Amount: $1,296,446 Topic: N101-014

SeaLandAire is providing this Phase II.5 proposal for the SBIR Topic # N101-014 (High Gain Array of Velocity Sensors, also known as Digital DIFAR Vertical Line Array or DDVLA) in response to the request for proposal received from NAVAIR and PMA-264. The DDVLA sonobuoy will provide increased acoustic performance in certain ocean environments taking advantage of ocean phenomena. This proposal has been generated based on both our Phase II effort and key performance specifications provided by the Navy for this effort. The focus of this Phase II.5 effort is to improve acoustics of the DDVLA prototype and further develop critical subassemblies toward a production sonobuoy (e.g. A-size form factor, reduced cost, etc.).

Multi-Sensor Sonobuoy

Amount: $139,982 Topic: N192-060

Exploring methods to increase passive detection ranges using data fusion of acoustic, e-field, and magnetic sensors. Each sensor has unique benefits and limitations, offering the promise of improving the overall system performance. Since the noise mechanisms are not coherent across the heterogeneous sensor modalities, the fusion offers promise over any single method on its own.

Compact Low Noise Acoustic Sensors for Sonobuoys

Amount: $124,997 Topic: N182-136

As foreign submarines become increasingly quieter, there is an ever-present need to improve the performance of passive surveillance systems to increase the probability of detection and ability to resolve critical signature differences useful for classification. Passive acoustic surveillance system such as sonobuoys typically employ arrays of hydrophones, configured to discriminate against background ocean noise. Generally speaking, the larger the array, the better noise performance it will have due to more directionality. The problem for sonobuoy based airborne Anti Submarine Warfare (ASW) have a strict volume and weight constraint; presently the US depends strictly on A-size form factor (4 7/8” x 36”) sonobuoys for a variety of reasons. Therefore, development of small sensor technology is particularly important as the US Navy seeks to remain at the forefront of the international ASW technology race. The issue of space within an A-size buoy presents the opportunity to develop a new, miniaturized acoustic sensor. SeaLandAire proposes to work in conjunction with Undersea Sensor Systems, Inc. (USSI), attacking the development challenges from a sonobuoy systems-engineering perspective. This teaming approach and systems perspective are important non-technical factors to ensure this SBIR funded effort can successfully transition to fleet use.

Ultra Low Frequency (ULF) Sonobuoy

Amount: $1,431,926 Topic: N07-121

For the Phase I effort the target low end frequency was 0.02 Hz. This necessitated the need for a horizontal fiber optic slack line and Neutrally Buoyant Sensor Package with active buoyancy control to isolate the sensor from flow and sea state induced mechanical noise. For Phase II the low end frequency has been changed to 1.0 Hz. This is a significant change and allows the use of a passive multi-element isolation suspension system and flow shield to isolate the sensor from flow and sea state induced mechanical noise. This has several advantages including: lower development cost, lower production cost, and better accuracy on target location (with a horizontal slack line the sensor package drifts away from the surface unit complicating data processing). Lower cost will be realized across mechanical, electrical and acoustic systems. The change in low end frequency also opens up opportunities in acoustic sensor design and selection. Another change from Phase I to Phase II is the requirement for a 3 axis vector sensor and omni directional hydrophone to allow a down looking cardioid beam pattern.
