Navy

In 1786 Tipu Sultan, again following the lead of his father, decided to build a navy consisting of 20 battleships of 72 cannons and 20 frigates of 65 cannons. In the year 1790 he appointed Kamaluddin as his Mir Bahar and established massive dockyards at Jamalabad and Majidabad. Tipu Sultan's board of admiralty consisted of 11 commanders in service of a Mir Yam. A Mir Yam led 30 admirals and each one of them had two ships. Tipu Sultan ordered that the ships have copper-bottoms, an idea that increased the longevity of the ships and was introduced to Tipu by Admiral Suffren.
