-L-3 Klein Associates introduces the Klein 7180 improved Long-Range Sonar (LRSSS) designed by Lloyd Huff and Peter Runciman. The system was made for NOAA Fisheries for fish-habitat research. The system provides calibrated backscatter across the entire survey area. This is accomplished with an innovative “cascade calibration” that uses overlapping swaths of data to transfer the calibrated backscatter from a simple downward-looking sonar (altimeter) to the other acoustic subsystems covering the nadir (under the towfish) and the outlying side-scan regions.

2013 - L-3 Klein Associates went into production with its S5900 Side Scan Sonar with “advanced multi-function sonar platform that included high resolution multi-beam side scan sonar, swath bathymetry sonar, swath bathymetry sonar, gap filler sonar and integrated tow body sensor and subsystems.”

-A Lake Champlain Maritime Museum project deployed a Klein 4900 Side Scan Sonar system from the R/V David Folger in a shipwreck survey off Burlington, Vermont (Lake Champlain). Dr. Tom Manley (Middlebury College, Middlebury, Vermont) assisted in the remote sensing survey.  The team used the sonar to image the 63 ft. long Burlington Horse Ferry shipwreck.  Jim Kennard and Scott Hill originally found the unusual watercraft during a 1983 side scan sonar project.  Several horse-powered ferry vessels were in use on the waterway from 1820-1850.  Today the sunken vessel is part of a Vermont shipwreck preserve system for visiting scuba divers.  Imagery from the 2016 project will help submerged cultural resource specialists in their management planning for this underwater heritage site.

-Parks Canada procured an Iver3 AUV (autonomous underwater vehicle) equipped with a variety of survey equipment including a Klein UUV 3500 SSS for use in future underwater searches of the 1845 Franklin expedition's HMS Erebus and HMS Terror shipwreck site areas in the Arctic waters of Canada.

2017 - Klein Marine Systems was instrumental in a successful survey of World War II-era “Upkeep” and “Highball” bombs resting in a loch in western Scotland.  Sir Barnes Wallis, designer of the Wellington bomber and R100 airship, developed the ordnance as tests for his “bouncing” bombs.  That weapon was deployed from British aircraft and the unique weapons destroyed the Rhur dams in Germany.  The ordnance was modified and also used as weaponry against enemy ships.  A Klein System 4900 was used in the survey and recovery project that included an Aspect Surveys vessel with support from Unique Systems-GSE Rentals.

-Atlantic Wreck Salvage (AWS), owner and operator of D/V Tenacious, announced today the discovery of a submarine off the Delmarva Peninsula. The vessel has yet to be dived and visually identified, but based on side scan sonar data, the location, and the historical record, the team firmly believes it to be the wreckage of the R-8 (S.S. 85), an American submarine dispatched by experimental aerial bomb testing in 1936. The discovery is historically important because R-8 is one of few American submarines resting in diveable East Coast waters that had yet to be located.
