The Bhubaneshwar class destroyers have been on the planning table for a couple of years, but kept getting bumped due to other concerns.

The class was added to the books for 1930-31, and incorporated changes already deemed necessary from operational experience. This included the deletion of the torpedo well forward of the bridge, as still seen in the Bassein class, with two quadruple carriages sited amidships. The torpedo armament was to be further doubled with the carrying of a full set of reload weapons. There was also to be an increase in light AA and searchlights, but the main gun armament was to remain at one gun forward and three aft.

This arrangement was finally discredited, after several years of inconclusive internal controversy, by the Filipino Revolution. It was found that a single forward gun was an inadequate armament when destroyers were either attacking or intercepting one; the volume of fire was simply ineffective. Rather than delay the class by re-designing it with a super-firing "Bruno" mount, the gun in "Anton" position was re-designated as a twin mount with much less fuss. The additional top-weight, however, meant that the torpedo reloads had to go.

Two units are planned for 1930, with two more for 1931. It is expected that the follow-up Miraj class of 1932 will be incremental improvements on this class.

Note: L:B ratio is 10.67:1, and the BC as entered is .395, not .40.

These former South African torpedo-boats were purchased in late 1931 as the Indian Navy deemed it necessary to acquire additional light craft for blockade and quarantine operations resulting from El Derretir. While there is some need to modify the light armament, it is expected that refits will not take place until after the crisis is ended.

The Miraj class destroyers, like the Ahmadabad class cruisers, have been designed for the specific purpose of escorting the Talwar class aircraft carriers. To this end, there have been several changes from the preceding Bhubaneshwar class destroyers.

The gun armament has been increased to six guns, concentrated in three dual-purpose mounts. This is one less mount than found in the Bhubaneshwar, which has freed up space for additional anti-aircraft weapons. An additional twin 35 mm is installed aft, and a second 15 mm quadruple mount has also been added.

The ASW fit includes the standard depth charge racks aft and four depth-charge throwers amidships. A non-publicized addition is the enlargement of the sonar dome to accommodate a second oscillator angled at thrity five degrees from the horizontal (versus the ten degrees offset of the primary oscillator). In theory, this second oscillator will be used during an attack run, where the steeper angle should allow for contacts to be maintained longer - leading to a more accurate attack.

Speed has decreased as a result of the heavier armament and, as importantly, the longer operating range. The additional bunkerage has been supplied so that carrier operations are not too inhibited by a need to refuel escorts.

A less dramatic change from the Bhubaneshwar class is the different hull form, with a long, sloping forecastle that levels out aft of the second funnel. This should keep the forecastle dry and allow for decent seakeeping, while not costing too much hull strength.

Six untis are planned for 1933, two more for 1934.
