NavyRecognition reports, “GeoSpectrum Technologies Inc. is pleased to announce that it has received a contract through the Build in Canada Innovation Program. Defence Research and Development Canada will test the TRAPS (Towed Reelable Active Passive Sonar) variable depth ASW sonar on Royal Canadian Navy ships.”
This system is seen as a possibility for both the twelve Kingston class “Coastal Defense Vessels” (970 tons, slightly smaller than the 210s) and the projected six icebreaking Arctic Offshore Patrol Ships. There is apparently no intention of using these on the more capable frigates.
The system can be fitted in a standard sized 20 foot container.
“The modular design of TRAPS provides a variety of installation options, including containerization on multi-mission vessels and standard deck-mounting.
“The TRAPS system is ideal for small combatants such as OPVs, corvettes, ships of opportunity, and USVs. Applications include naval defence/surveillance, drug interdiction, homeland security, and other water-borne policing.”
In addition to detecting submarines and surface vessels, the system is claimed to be usable for:
- Active torpedo detection
- Torpedo decoy
- Passive receiver
- Black box pinger detection
- Sonobuoy processor
A typical detection range of 50 nautical miles is claimed. If it works as advertised this might give most of our larger ships an ASW capability and perhaps help us detect semi-submersibles. Thales’ CAPTAS series is similar, with CAPTAS 2 and CAPTAS 1, designed for ships of over 1,500 and 300 tons respectively.

Can this system be used for mine countermeasures?
Probably not. Typically you need very high frequency sonar to get an accurate enough picture to detect small objects like mines, while you need lower frequencies to give the range you need to detect submarines at a useful range.
Thanks for the info
