India's Next-Generation Destroyer: Balancing Size and Efficiency

The Challenge of Crewing India's Next-Generation Destroyer

The Indian Navy's proposed Project 18 destroyer is a behemoth, with a projected weight of 10,000 tonnes. This massive size comes with a significant challenge: crewing. The Indian Navy's current destroyers, such as the Kolkata-class, have a displacement of about 7,400 tonnes and officially carry around 330 personnel. However, as the ship's size and complexity grow, so does the challenge of crewing.

The US Navy's Zumwalt-Class Destroyer: A Potential Solution

The US Navy's Zumwalt-class destroyer offers a potential solution to this challenge. With a crew of just 197, these ships have harnessed automation to reduce personnel. The Total Ship Computing Environment links together the ship's machinery, sensors, communication systems, and other functions via a common network. This integrated approach allows for predictive maintenance, reducing the need for manual inspections and increasing the value of automated monitoring.

Automation in Combat Information Centre

The combat information centre is another area where automation can play a significant role. The radar, electronic warfare, sonar, and electro-optical sensors of Project 18 should be incorporated into a common combat-management architecture, which can automatically correlate contacts and display a single tactical picture. This would decrease the amount of duplication among radar operators, electronic-warfare personnel, and other sensor operators, reducing the routine workload associated with gathering, filtering, and correlating information.

Navigation and Bridge Operations

Integrated electro-optical sensors, radar, AIS inputs, electronic charts, and automated collision-avoidance assistance can lessen the routine workload of the bridge crew. Although human watchkeepers would still be essential, especially in combat situations, in poor weather, and when operating in congested waters, automation might reduce the number of seamen needed for normal steaming.

Damage Control

Automated systems are capable of detecting flooding, fire, smoke, changes in temperature, and a loss of electrical power and will then automatically trigger the appropriate isolation or suppression systems. However, the ship cannot be certain that the automation will always work following battle damage. A key lesson derived from the idea of highly automated warships is that if the crew is reduced too much, it may lead to weaknesses should several systems fail at the same time or if a damaged ship needs a large number of personnel for firefighting, getting casualties out, and carrying out manual repairs.

A Realistic Aim for Project 18

Research into the Zumwalt concept has pointed out worries about workload, damage control, and the practical limits of having an extremely small crew. Project 18 should therefore aim for manning which is assisted by automation rather than manning which is dependent on automation. If we take the number of about 330 personnel on the Kolkata-class as our base figure, a realistic aim would be to reduce the number of personnel on a Project 18 ship to between 220 and 250, depending on the final mission requirements.
