What Sealertec does

Sealartec is an Israeli defense-technology company that develops fully autonomous launch, recovery, and replenishment systems for unmanned surface vehicles (USVs) and unmanned underwater vehicles (UUVs). Its product portfolio comprises four core systems — ALR-C (crane/davit capture), ALR-S (stern-ramp conversion), ALR-U (UUV surface recovery), and A-RAS (autonomous at-sea refueling and data transfer) — all built on a proprietary GPS-free Local Positioning System (LPS). The systems use AI-driven adaptive control and real-time sensor fusion to perform launch and recovery operations in sea states up to 6 without human intervention, with stated performance metrics including sub-1.5-second capture and sub-15-second hauling for ALR-C, and 757 L/15 min refueling throughput for A-RAS. The company was founded in 2015, is headquartered in Caesarea, Israel, and operates with a small team (1–15 employees).

The business model is enterprise hardware-and-integration sales targeting navies, coast guards, and tier-one defense prime contractors, supplemented by technology licensing to USV manufacturers. Named customers and integrators include the U.S. Navy (validated through the JPEM Stiletto Program in June 2025), BAE Systems, MARTAC, Israel Aerospace Industries, the Israeli Ministry of Defense, and NAVSEA. Pricing is custom and quote-based, not publicly disclosed. Distribution runs through direct enterprise sales and OEM-style partnerships in which Sealartec's systems are embedded into third-party platforms (e.g., MARTAC's Devil Ray T38). The company markets through thought-leadership content (a CEO-authored blog positioned as "the guru of launch and recovery"), LinkedIn, YouTube demos, and major defense industry conferences (Sea-Air-Space 2025, Navy Tech Helsinki 2025). Only one disclosed funding round exists — a $115,000 seed from HiCenter Ventures in February 2024 — which is unusually small relative to the customer roster and suggests either imminent institutional capital or substantial reliance on non-dilutive defense contracts and grants.

Core offering

Sealartec develops and delivers fully autonomous launch and recovery (ALR) systems for unmanned surface vehicles (USVs), unmanned underwater vehicles (UUVs), and manned boats. Their portfolio includes ALR-C (cradle/davit recovery), ALR-S (stern ramp recovery), ALR-U (UUV surface recovery), and A-RAS (autonomous at-sea replenishment), all powered by a proprietary GPS-free Local Positioning System (LPS). These systems enable deployment and retrieval of marine vessels without human intervention, operating in sea states up to 6.

Product overview

Sealartec offers a modular portfolio of autonomous launch and recovery systems for unmanned and manned marine vehicles. The core product family includes ALR-C (for davit/crane applications), ALR-S (for stern ramp recovery), and ALR-U (for UUV recovery), all powered by the proprietary Local Positioning System (LPS). The A-RAS system extends capabilities to autonomous at-sea replenishment. These products work together to enable fully autonomous deployment, recovery, and servicing of USVs and UUVs even in extreme sea conditions up to Sea State 6.

Functional benefit

Products and services

• ALR-C (Autonomous Launch and Recovery - Cradle) Fully autonomous system for retrieval of USVs and manned boats via davits or cranes. Features rapid capture under 1.5 seconds and hauling under 15 seconds, with autonomous capture initiation and recovery sequence. Fits any boat, any ship, any crane without requiring structural reinforcement of the boat.
• ALR-S (Autonomous Launch and Recovery - Stern) Converts standard stern ramps to fully autonomous recovery systems for USVs and manned boats. Operates in sea states up to 6. Designed as an add-on solution for existing stern ramps or newly built platforms.
• ALR-U (Autonomous Launch and Recovery - UUV) Self-maneuvering robotic system for secure UUV (Unmanned Underwater Vehicle) recoveries at distance from ship without human intervention. Operational to Sea State 5 with recovery time under 20 seconds.
• A-RAS (Autonomous Replenishment At Sea) Enables real-time data transfer and refueling of USVs while both vessels remain in motion, with minimal impact on both USVs and motherships. Supports refueling speed of 757 liters per 15 minutes, operational to Sea State 6, and requires no special equipment on host vessels.
• LPS (Local Positioning System) Proprietary GPS-free positioning solution that uses advanced sensor technology for real-time relative positioning data, enabling vessels to perform accurate maneuvers in areas with limited or no GPS signal such as congested ports or underwater regions.
