Two Agosta-class diesel-electric, ocean-going attack submarines were originally built in France and intended for export to South Africa (to operate as "Astrant" and "Adventurous"). However, the UN embargo on the African nation meant that these two boats were no longer allowed to be sold to, and delivered, to the prospective customer. In 1977, these two examples were then sold off to the Pakistan Navy under the Agosta-70-class name and taken on in 1979. They were PNS Hashmat (S135) and PNS Hurmat (S136).

The Agosta-70 boat fleet was eventually strengthened by the arrival of three boats based in the improved Agosta-90B-class design.

PNS Hashmat (S135) was the lead ship of the two strong Agosta-70 boats received by the Pakistan Navy. Her sister became PNS Hurmat (S136) in service. Today, both are active vessels in the service and operate alongside the three Agosta-90B-class boats lead by PNS Khalid (detailed elsewhere on this site).

The Agosta-70-class boats are in the 1940 ton displacement range and have conventional propulsion schemes and traditional submarine design arrangements. The crew complement is about 45, owing much to the relatively compact dimensions of the class. The sail is fitted well-forward of midships and a cruciform plane arrangement is seen at the stern. Dive planes are installed along the bow. Internally, the usual sonar, radar and electronic warfare fits are had. Armament is 4 x 533mm torpedo tubes facing the bow with support for launching the American-made Harpoon anti-ship missile being had. A naval dispensing quality is also built into the boat.
