Capability Developments

Major milestones and key developments of the capability

The Capability Development Index tracks the events that move a capability — operational use, technical breakthroughs, procurement decisions and the industrial base behind them — and places each on the record with the date it happened.

Recent developments cover the current period. Historical developments are the inflection points that produced Strategic Lift & Mobility as it stands today.

Historical Developments

1923US Army Air Service pilots completed the first sustained air-to-air refuelling, transferring fuel between two biplanes 103 years ago

A hose passed by hand between aircraft flying in close formation proved that one aircraft could extend another's endurance in flight, a demonstration that took decades to mature into routine tanker operations but established the basic principle still used today.

1942–1945Allied transport crews flew supplies over the Himalayas to China after Japan cut the Burma Road 84 years ago

Flying unpressurised aircraft over some of the world's highest terrain in severe weather, the route became the highest-volume airlift attempted up to that time and kept Chinese forces supplied for the rest of the war at a heavy cost in aircraft and crews.

1948–1949The Berlin Airlift sustained a blockaded city of some two million people entirely by air for almost a year 78 years ago

American and British aircraft landed at Berlin's airfields at a rate of roughly one every few minutes at the operation's peak, defeating a Soviet land blockade without a shot fired and establishing airlift as a tool of Cold War statecraft.

The airlift's success hardened the division of Germany and Europe
1954The C-130 Hercules made its first flight, beginning what became the most widely used tactical transport aircraft in history 72 years ago

Rugged, able to use short and unpaved runways, and continuously updated over seven decades, the design was still in production and in front-line service with dozens of air forces long after most contemporaries had been retired.

1957The KC-135 Stratotanker entered service as the first purpose-built jet aerial refuelling aircraft 69 years ago

Matching tanker speed to the new generation of jet bombers and fighters ended a mismatch that had limited refuelling with older piston-engined tankers, and variants of the aircraft remained in frontline US service for the rest of the century and beyond.

1973The United States ran Operation Nickel Grass, a strategic airlift resupplying Israel during the Yom Kippur War 53 years ago

US Air Force C-5s and C-141s delivered replacement aircraft, munitions and equipment directly into a live conflict, demonstrating that a strategic airlift decision made in Washington could shift the material balance of a war within days.

1976Israeli C-130 transports flew nearly 4,000 kilometres to rescue hostages held at Entebbe airport in Uganda 50 years ago

The raid combined long-range tactical airlift, in-flight planning and a night landing on unlit runways to insert and extract a rescue force far beyond Israel's borders, becoming a reference case for the reach that airlift gives special operations.

1982The Antonov An-124 Ruslan entered service as the world's largest series-produced transport aircraft 44 years ago

Its unmatched cargo volume made it the aircraft of choice for outsize industrial and military loads, and chartered An-124s became a standard part of global heavy-lift logistics for cargo too large for any Western freighter to carry.

1984India began sustaining troops on the Siachen Glacier almost entirely by helicopter and fixed-wing airdrop 42 years ago

After occupying the glacier ahead of Pakistan, India faced the task of supplying posts above 6,000 metres where no roads could reach, making the sector the longest-running example of a garrison kept alive by air mobility alone.

1988The Antonov An-225 Mriya first flew as the largest aircraft ever built, designed to carry the Soviet Buran space shuttle 38 years ago

Built to ferry the Soviet space shuttle programme's orbiter and boosters, the six-engine giant later found a commercial role hauling outsize cargo worldwide; the only completed airframe was destroyed on the ground near Kyiv in the early days of Russia's 2022 invasion.

Recent Developments

March 2025China, India and Russia airlifted rescue teams and relief supplies into Myanmar after a major earthquake last year

Military transport aircraft from several countries delivered search-and-rescue teams, field hospitals and aid within days of the quake that struck the Mandalay region, illustrating airlift as a fast-response tool independent of a country's own alliance network.

Myanmar's military government allowed only limited foreign access for relief flights
2025Embraer added European customers to the export list for its KC-390 Millennium transport last year

Austria and the Netherlands moved ahead with orders or transfers of the Brazilian-built tanker-transport, building on earlier sales to Portugal and Hungary and establishing Embraer as a credible alternative to established European and American airlifters.

2025India advanced a long-pursued programme to acquire dedicated aerial refuelling tankers last year

A procurement process for a small fleet of Airbus multi-role tanker aircraft moved forward after years of delay, aimed at closing a persistent gap in the Indian Air Force's ability to extend fighter range and endurance.

2025The World Food Programme and partner agencies ran airlifts and airdrops into Sudan and Chad amid access restrictions on land routes last year

Fighting and bureaucratic obstruction limited overland convoys into Sudan, pushing the United Nations and humanitarian partners toward costlier air deliveries to reach famine-affected areas, a stopgap that could carry only a fraction of what road transport would move.

2025Boeing continued fielding fixes to the KC-46 Pegasus tanker's remote vision system last year

The improved camera and display system, meant to correct years of refuelling boom control problems, moved through testing toward wider fielding, a step the US Air Force had treated as a condition for full confidence in the aircraft.

2025China expanded its Y-20 transport fleet and brought the Y-20U tanker variant into wider service last year

Growing numbers of domestically built airlifters and tankers reduced the People's Liberation Army's long-standing reliance on ageing Russian-made Il-76 aircraft, extending its capacity for long-range troop movement and mid-air refuelling of fighter and bomber fleets.

October 2024India inaugurated a final assembly line for C-295 transport aircraft at Vadodara 2 years ago

The Tata Advanced Systems facility, built with Airbus, was set to produce most of a 56-aircraft order to replace the Indian Air Force's Avro fleet and to become India's first private-sector military aircraft assembly line.

The line was intended to produce aircraft for export as well as India's own fleet
2024The Philippine Air Force took delivery of new C-130J Super Hercules aircraft 2 years ago

The newer aircraft began replacing a fleet of ageing C-130Bs and Ts that had suffered repeated accidents and low availability, restoring a more reliable heavy airlift capability for an archipelagic country dependent on air transport for disaster response.

2024NATO expanded its Multinational MRTT Fleet of shared aerial tankers 2 years ago

The Eindhoven-based multinational unit, which lets smaller air forces buy shared access to aerial refuelling and strategic airlift rather than each building a national fleet, added member nations and additional Airbus A330 aircraft to its pool.

The Czech Republic joined the pooled fleet as a newer member nation
2024Indonesia signed for the A400M, becoming the type's first Asian operator 2 years ago

The order for European-built airlifter-tankers gave Indonesia a heavy strategic lift and refuelling capability well beyond its existing Hercules fleet, part of a wider modernisation of its air force's transport and logistics arm.
