The Type 540 Gal-class submarine is a slightly modified variant of the German HDW Type 206 submarine class (which includes the distinctive dome, or bulge, in the front of the boat), modified for Israeli requirements. The Gal class submarines were built to Israeli specifications at the Vickers shipyards Type 540 at Barrow in Furness in the UK rather than Germany for political reasons. "GAL" (גל - Hebrew for "wave") was the name of the son of Abraham (Ivan) Dror, 3rd commander of the squadron and head of the project.

The Gal class of submarines were the first Israeli Navy submarines built to Israeli Navy specifications. They supplant previous generations of submarines employed from 1958 by the Israeli navy which were refurbished and upgraded boats of the British S class and T class; submarines whose hull designs dated back to the decade before World War II.

Since entering service in the late 1970s, these small but agile and sophisticated submarines were continuously upgraded with newer systems to maintain their technological edge. They were somewhat unusual in that all boats of the class were at one point equipped with six-tube retractable Blowpipe surface-to-air missile launchers controlled from inside the boat, though these were later removed. The Israeli newspaper Maariv reports that Gal-class submarines were active in the 1982 Lebanon War. During 1983 torpedo tube launched Sub-Harpoon anti-ship missiles and associated fire control systems were added to all boats of the Gal class. NT 37E torpedoes were acquired to replace the older Mk 37 models in 1987–88. All extensively overhauled in 1994–95, including improved sensors and fire control system. In the late 1990s, the Gal submarines were replaced with the new, much larger Dolphin-class submarines. The Gal boats were decommissioned in the early 2000s. One was scrapped and two were sent to HDW in Germany in hopes of finding a foreign buyer. When none was found, in October 2007 Gal was shipped back to Haifa, Israel and is now on display in the Israeli Naval Museum. Some changes were made in the submarine to make it accessible to visitors, such as an entrance cut into her side.
