Indian Navy releases an RFI for the development of Underwater Launched Autonomous Underwater Vehicle

The ULAUV project aims to enhance the operational effectiveness of underwater platforms by enabling them to perform crucial roles such as Intelligence, Surveillance, and Reconnaissance (ISR), Mine Counter Measures (MCM), and Deception Operations. This autonomous vehicle is specifically designed to operate seamlessly from underwater platforms, thereby supporting vital maritime security and defense operations.

Functional and Operational Requirements

The ULAUV should be equipped with essential capabilities:

• Detection Capabilities: Utilizes integral sensors for detecting surface and sub-surface contacts.

• Communication: Features acoustic communication links to transmit target information to other underwater platforms.

• Data Collection: Capable of recording acoustic and visual data for detailed analysis.

• Homing Features: Includes capabilities to locate distressed underwater platforms by homing in on specific distress frequencies.

Key Performance Parameters:

• Maximum Speed: Achieves speeds of ≥5 knots under optimal conditions.

• Endurance: Maintains operational capability for more than 24 hours at cruising speed.

• Operation Cycle: Ensures an operational cycle of at least 18 months.

• Propulsion: Uses electric motor and propeller designed for high efficiency and low acoustic noise.

• Navigation: Employs Inertial Navigation System (INS) and differential GPS with anti-jamming features for precise navigation.

• Power and Battery Management: Incorporates robust management systems for efficient power usage.

Testing and Certification

The prototype development should adhere to MIL-grade components, ensuring reliability and performance in challenging underwater environments. Commercial Off-The-Shelf (COTS) items are ruggedized to meet Technical Evaluation Committee (TEC) standards, ensuring suitability for operational deployment.
