The recent third joint working group meeting of the UK-India Electric Propulsion Capability Partnership, held at Portsmouth Naval Base, marked a significant milestone in the collaborative efforts between the two nations to enhance the Indian Navy’s technological capabilities. Co-chaired by Rear Admiral Steve McCarthy from the UK and Joint Secretary for Naval Systems Rajeev Prakash from India, this meeting culminated in the signing of a Statement of Intent on Cooperation for the Design and Development of Electric Propulsion Systems for the Indian Navy. This agreement, signed on November 28, underscores a mutual commitment to fostering indigenous development of advanced naval technologies.
The Electric Propulsion Capability Partnership is pivotal in addressing the evolving demands of modern naval warfare. As both nations strive to modernize their fleets, the focus on electric propulsion systems represents a forward-thinking approach to naval engineering. The establishment of a subordinate working group to develop an Implementing Arrangement (IA) indicates a structured pathway towards realizing these technological advancements. Upon review and signing of the IA, the program is poised to accelerate toward its launch phase, emphasizing equipping the Indian Navy’s new Landing Dock Platforms (LPDs), projected for deployment by 2030.
The collaboration draws upon the UK’s extensive experience in electric propulsion technology, particularly lessons learned from the development of various classes of vessels, including the Type 23 frigates, Type 45 destroyers, and the Queen Elizabeth class aircraft carriers. This wealth of knowledge is invaluable in guiding the design and implementation of electric propulsion systems tailored to the specific operational requirements of the Indian Navy.
Electric propulsion technology offers several compelling advantages that align with contemporary naval priorities. Firstly, the environmental benefits are significant; electric propulsion systems produce lower emissions compared to traditional diesel generators, contributing to cleaner naval operations. Additionally, these systems are characterized by reduced noise and vibration, which is crucial for stealth operations in naval warfare. The quietness of electric drives enhances the tactical advantage of naval vessels, allowing them to operate more discreetly in contested environments.
Moreover, the reliability and operational efficiency of electric propulsion systems cannot be overstated. Modern naval vessels, such as aircraft carriers and destroyers, do not require permanent crew presence in engine rooms, as these systems can be monitored and managed remotely. This not only reduces the crew’s workload but also extends the intervals between servicing and maintenance, thereby increasing the vessel’s availability and utility. Enhanced response times during operational scenarios further illustrate the superiority of electric propulsion, allowing for smoother manoeuvring and rapid acceleration when necessary.
A striking example of this efficiency is evident when comparing the UK’s former Invincible Class aircraft carriers, which weighed approximately 22,000 tons and were equipped with four gas turbines and eight diesel generators, to the new Queen Elizabeth class carriers, which, at 65,000 tons, utilize only two gas turbines and four diesel engines. Despite the significant increase in size and capabilities, the crew size remains comparable to that of the smaller Invincible class, highlighting the advancements in technology and operational efficiency.
The UK-India Electric Propulsion Capability Partnership represents a strategic initiative that not only enhances the Indian Navy’s technological capabilities but also strengthens the defence ties between the two nations. The commitment to developing electric propulsion systems reflects a broader trend toward sustainable and efficient naval operations. As both countries move forward in this partnership, the potential for innovation and the advancement of naval warfare capabilities is immense, paving the way for a more resilient and technologically advanced maritime force.
