This Week in Defence Technology
This week’s developments point to a widening definition of the military industrial base. Advanced capability is increasingly determined not only by the ability to manufacture aircraft, ships and missiles, but also by mastery of propulsion, semiconductors, autonomous systems, space infrastructure, testing facilities and the industrial processes that allow technology to be improved rapidly.
For India, the most strategically significant announcement was a proposed Reliance Industries–Rolls-Royce partnership to develop an indigenous combat-aircraft engine. Elsewhere, developments in gallium-nitride electronics, autonomous aviation, space-domain awareness, resilient satellite networking and high-speed weapons testing illustrate the technologies and supporting infrastructure that increasingly determine national military-industrial strength.
Importantly, some developments this week were technology demonstrations or completed milestones, while others remain proposals or industrial agreements. Those distinctions matter.
Land Systems
One notable development concerned protection of military installations against increasingly inexpensive aerial threats.
On 12 August, U.S. Air Combat Command described work by its Point Defense Task Force to test approaches for protecting air bases against threats including drones and cruise missiles. The effort involves testing and analysis rather than announcement of a single new operational weapon. (Afghanistan Military)
The industrial lesson extends beyond air-base defence. Counter-UAS capability increasingly requires a combination of radar, electro-optical sensors, electronic warfare, command-and-control software and kinetic or non-kinetic effectors.
This makes counter-drone defence an industrial ecosystem rather than a single-product market. Countries able to manufacture sensors, communications equipment, electronic-warfare systems and affordable interceptors in volume will have a considerable advantage in sustaining layered defence.
Air & Aerospace
India takes a significant step toward fighter-engine sovereignty
On 14 August, Reliance Industries and Rolls-Royce announced their strategic intent to jointly offer the design, development, manufacture and delivery of a sovereign indigenous combat engine for India’s Advanced Medium Combat Aircraft programme. (Rolls-Royce)
The companies also said they would explore establishing an Aerospace Gas Turbine Complex in India as a centre of excellence for power and propulsion technology. (Rolls-Royce)
This is an industrial proposal, not yet a completed indigenous engine programme. That distinction is important.
Nevertheless, its significance is difficult to overstate.
Combat-aircraft engines sit near the top of the defence-technology hierarchy. Developing them requires competence in turbine aerodynamics, combustion, high-temperature materials, single-crystal or advanced turbine components, coatings, precision manufacturing, control systems, testing and long-term sustainment.
If India eventually acquires genuine design and development capability rather than primarily manufacturing an overseas design, the benefits could extend beyond AMCA into future aircraft, unmanned systems, marine gas turbines and advanced industrial technologies.
For a military industrial base, propulsion capability compounds: knowledge accumulated in one generation of engines can support the next.
Maritime & Undersea
Australia’s Hunter-class frigate programme offered a useful industrial-base example this week.
BAE Systems Australia reported on 12 August that the prototyping phase of the Hunter-class programme had concluded, following work at the Osborne Naval Shipyard and Henderson facility. One ship is already under construction, with preparations continuing for subsequent vessels. (BAE Systems)
Prototyping can look less dramatic than a ship launch, but it is a critical part of sovereign naval capability.
It allows shipyards to validate manufacturing sequences, train workers, identify design problems, develop supplier relationships and establish repeatable production processes before full-rate construction.
For nations seeking to rebuild shipbuilding capacity, the limiting factor is often not access to a warship design. It is the ability to establish the skilled workforce, infrastructure, suppliers and production discipline required to build complex vessels repeatedly.
That is industrial-base capability in its most tangible form.
Space & Cyber
Two U.S. Space Force developments illustrate how space capability is becoming increasingly distributed and resilient.
On 14 August, the U.S. Space Force and Japan successfully launched a U.S. sovereign space-domain-awareness payload aboard Japan’s QZS-7 satellite. (SSC Space Force)
This was a completed launch rather than a proposed programme.
The previous day, Space Systems Command announced investment in a resilient multi-vendor architecture for a next-generation Space Data Network. (SSC Space Force)
The industrial significance lies in diversification.
Traditional military space architectures often depended on small numbers of extremely sophisticated satellites and specialised ground systems. More resilient architectures increasingly emphasise distributed networks, multiple suppliers, proliferated spacecraft and interchangeable communications pathways.
This has consequences for the industrial base. A country seeking serious military-space capability needs more than rockets and satellites. It needs optical systems, electronics, secure communications, software, data processing, ground infrastructure, cybersecurity and a continuing manufacturing pipeline.
Space power therefore increasingly resembles an industrial network rather than a collection of individual satellites.
Electronics, Sensors & Communications
One of the week’s most technically important developments occurred below the level of complete weapons systems.
On 12 August, BAE Systems announced that its FAST Labs organisation had completed Phase 1 of DARPA’s THREADS — Technologies for Heat Removal in Electronics at the Device Scale — programme and had moved into Phase 2. (BAE Systems)
THREADS is addressing thermal limitations affecting high-performance gallium nitride, or GaN, radio-frequency electronics. BAE says successful thermal-management improvements could substantially increase the range of RF systems. Work involves its Microelectronics Center and several U.S. universities and technology organisations. (BAE Systems)
Why does this matter?
GaN electronics are important to advanced radar, electronic warfare and communications because they can operate at high power and frequency. But increased power also produces heat.
Improving the ability to remove that heat can allow military radars and electronic systems to operate more effectively without proportionately increasing size and weight.
This demonstrates why semiconductor technology is now a strategic defence capability.
A nation may manufacture aircraft and ships domestically but remain dependent if critical RF components, processors and semiconductor fabrication remain externally controlled.
Propulsion, Materials & Manufacturing
The Reliance–Rolls-Royce announcement is therefore more than an aerospace story. It belongs equally in the manufacturing and materials discussion.
The proposed Indian gas-turbine complex would require a domestic ecosystem capable of producing extremely demanding components consistently and at scale. (Rolls-Royce)
Such capability normally spreads through a supply chain: specialist alloys, precision machining, coatings, casting, metrology, instrumentation, test equipment and engineering software all benefit.
The United States provided another example of the importance of supporting infrastructure on 18 August.
The U.S. Navy’s Naval Surface Warfare Center Crane and the Indiana National Guard unveiled what they describe as the country’s first ground-based sled-track capability for accelerating defence innovation. The high-speed test facility is intended to reproduce conditions associated with advanced flight and weapons technologies. (Naval Sea Systems Command)
Testing infrastructure rarely receives the attention given to weapons.
Yet sophisticated weapons cannot be developed reliably without ranges, wind tunnels, propulsion stands, environmental chambers, electronic-warfare laboratories, materials facilities and instrumentation.
A country’s defence industrial base therefore consists partly of factories — and partly of the facilities that allow factories and laboratories to discover whether their technology actually works.
The distinction between owning a missile and owning the capability to continuously develop missiles is fundamental.
Industrial Base Implications
The clearest lesson from this week is that national military-industrial capability exists in layers.
At the visible level are aircraft, frigates, drones and missiles.
Below them sit engines, radars, sensors, electronic-warfare equipment and communications.
Below those sit semiconductors, advanced materials, specialised manufacturing processes and software.
And supporting the entire system are laboratories, test facilities, universities, engineering skills and production infrastructure.
India’s current defence-industrial expansion provides useful context. Government figures published during this period put domestic defence production at a record ₹1.78 lakh crore in FY2025–26, up 15.6% from the previous year. Defence exports reached ₹38,424 crore, with Indian defence products reaching more than 80 countries. (Press Information Bureau)
The private sector accounted for approximately 24% of India’s defence production, while public-sector entities accounted for about 76%. (Press Information Bureau)
Those numbers demonstrate increased capacity, but the next test is technological depth.
Can more critical technologies — engines, seekers, sensors, semiconductor devices, materials, propulsion systems and advanced manufacturing processes — also be designed and continuously improved domestically?
That is where the difference between defence manufacturing and a genuinely self-reinforcing military industrial base becomes visible.
A country can licence-produce an advanced system.
A stronger industrial base can understand it, sustain it, modify it, improve it and eventually create its successor.
