What DSIT does

DSIT Solutions Ltd. is an Israeli underwater-acoustic technology company founded in 1993 and headquartered in Givat Shmuel. It is a subsidiary of Rafael Advanced Defense Systems Ltd. and completed its IPO on the Tel Aviv Stock Exchange in March 2026. The company designs, develops, and integrates sonar and acoustic systems for naval defense, homeland security, and critical-infrastructure protection, anchored by its Shield™ product family (AquaShield DDS, PointShield PDDS, BlueShield, SeaShield, KnightShield), Anti-Submarine Warfare systems (BlackFish HMS/BMS, SwordFish TAS, DogFish, GhostFin), the WhitePointer underwater communication system, and acoustic analysis/trainer products (PAR, UASA). These are increasingly sold as the integrated Underwater Domain Awareness (UDA) solution, which layers multiple sonar modalities with AI/ML-powered detection, classification, and tracking for continuous 24/7 monitoring of underwater threats.

The company generates revenue primarily through project-based, multi-year defense and homeland security contracts with government ministries, navies, coast guards, and energy operators, awarded via competitive tenders and direct negotiations. Pricing is bespoke with no standard tiers; the company reinvests more than 10% of revenue into R&D. Go-to-market combines enterprise field sales, an active international defense exhibition circuit (Euronaval, IMDEX Asia, DSEI UK/Japan, Navy Tech & Seabed Defence), exclusive reseller agreements for specific geographies (KeepZone AI for Mexico), and distribution leverage from its parent Rafael. Key customers include the Israeli Ministry of Defense (anchor), a leading NATO Navy, the Republic of Korea Navy, Energean (Karish-Tanin energy installation), and Mexico government/energy operators. The company holds ISO 9001, ISO 27001, ISO 45001, and ISO 14001 certifications, and its underwater communication product complies with NATO STANAG 1074.

Revenue model

1. Defense and Homeland Security Systems Sales: DSIT generates revenue primarily from selling sonar-based underwater defense and security systems to government defense ministries, navies, and homeland security agencies. Revenue is project-based with long sales cycles involving tender processes, demonstrations, and contract negotiations. Products include turnkey systems, subsystems, and integrated solutions. The company invests over 10% of revenue in R&D and maintains independent capabilities.
2. R&D and Technology Development: DSIT invests over 10% of revenue in Research and Development, generating solutions at the forefront of underwater acoustic technology while maintaining cost-benefit ratios for customers. This continuous R&D investment supports ongoing product improvements, new product development (e.g., GhostFin for UUVs), and technology evolution across the sonar product family.
3. UUV Sonar and Prototype Systems: DSIT secured a $6.87 million agreement to supply prototypes of advanced underwater acoustic sonar systems and acoustic signal analysis systems for unmanned underwater vehicles (UUVs), demonstrating expansion into the unmanned platforms market segment.
