How HAL Makes Money From Tejas, Helicopters and Aircraft Maintenance

Hindustan Aeronautics Limited is usually associated with fighter jets, helicopters and military aircraft, but a large part of its business begins after those aircraft have already been delivered.

HAL earns from building platforms such as Tejas, Dhruv, Prachand and Dornier aircraft, but it also earns repeatedly from maintaining, repairing, overhauling and upgrading them throughout their operating lives.

That lifecycle model is one of the most important parts of the business.

In FY26, HAL reported about ₹33,089 crore of revenue from operations and roughly ₹9,076 crore of profit after tax. Its order book stood at about ₹2.55 lakh crore, giving the company visibility across aircraft, helicopters, engines and repair contracts for several years.

The interesting part is that HAL is not dependent on one large aircraft order. It can earn during development, manufacturing, delivery, engine production, spare-parts supply and decades of maintenance after the aircraft enters service.

Aircraft maintenance is still HAL's biggest business

HAL's largest revenue stream today comes from repair and overhaul rather than new aircraft manufacturing.

In FY26, the company generated roughly ₹20,524 crore from repair and overhaul, compared with around ₹9,227 crore from manufacturing.

That difference explains how HAL's economics work.

Military aircraft are designed to remain in service for decades. During that time, engines need overhaul, components wear out, avionics require servicing and aircraft periodically return for scheduled maintenance.

HAL supports a large installed fleet across the Indian Armed Forces, which creates recurring work year after year.

A fighter aircraft delivered today can therefore continue generating revenue for HAL long after the original manufacturing contract has been completed.

This makes maintenance much more than a supporting business. It is one of the company's most dependable revenue engines.

Tejas is becoming one of HAL's biggest manufacturing opportunities

The Tejas programme is central to HAL's next phase of growth.

HAL has already delivered aircraft under the original Tejas Mk1 programme and now has a much larger production pipeline through the Mk1A version.

The company already had an order for 83 Tejas Mk1A aircraft, and during FY26 it received another large contract covering 97 additional aircraft.

That gives HAL a long manufacturing runway.

The economics begin with the aircraft itself, but they do not stop there. Every Tejas entering service adds another aircraft to HAL's future maintenance and support base.

Over time, those aircraft will require spare parts, repairs, upgrades and component replacement.

The same programme can therefore create two separate revenue streams: manufacturing revenue in the near term and recurring lifecycle revenue over many years.

This is why a growing manufacturing order book also supports HAL's future MRO business.

Delivery matters more than the headline order value

A large defence contract does not immediately become revenue.

HAL recognises manufacturing revenue as aircraft and other products move through production and are accepted by the customer.

That distinction became especially important with the Tejas Mk1A programme.

The order was already in place, but shortages and delays involving GE F404 engines affected the pace at which HAL could complete and deliver aircraft.

This shows one of the main risks in HAL's business model.

Demand is often secured years in advance, but the company still depends on suppliers, production capacity and imported components before that demand can turn into reported revenue.

A ₹50,000 crore contract can give visibility, but annual revenue depends on how quickly HAL can physically manufacture and deliver the product.

For HAL, execution is often more important than finding customers.

Helicopters create another long revenue cycle

HAL also has a large helicopter business spanning platforms such as Dhruv ALH, Rudra, Light Combat Helicopter Prachand and Light Utility Helicopter.

These programmes generate revenue in much the same way as fighter aircraft.

HAL earns when new helicopters are manufactured and delivered, but it also earns later from spare parts, engine work, upgrades and maintenance.

This makes the installed fleet increasingly valuable over time.

As more Dhruv, Prachand and other helicopters enter service, HAL's future support requirement grows alongside the manufacturing business.

The company also has future helicopter programmes under development, which could extend this cycle further.

This means today's production orders can become tomorrow's recurring maintenance revenue.

Aero-engines are another major part of the business

HAL is not only an aircraft assembler. It also manufactures and overhauls aero-engines.

One of its largest recent engine contracts covers 240 AL-31FP engines used in India's Su-30MKI fleet. The contract was valued at around ₹25,350 crore.

Engines are especially attractive from a lifecycle perspective because they require repeated maintenance throughout an aircraft's life.

An engine does not remain untouched for decades. It goes through scheduled inspections, component changes and overhaul cycles, giving HAL repeated opportunities to earn service revenue.

The company also works on other engine programmes, including RD-33 engines, while building new partnerships with global aerospace companies.

Its collaboration with Safran on the Aravalli helicopter engine and its work connected to CFM LEAP engine components show that HAL is trying to build a broader aerospace-engine business rather than remain dependent only on legacy military programmes.

HAL earns throughout the life of an aircraft

The easiest way to understand HAL is to look at the full aircraft lifecycle.

The first stage is development.

HAL can participate in designing and developing new aircraft, helicopters, engines and systems, generating revenue through development contracts and milestone-based work.

The second stage is manufacturing.

Once the programme moves into production, HAL earns from building and delivering the aircraft, helicopter, engine or system.

The third stage begins after delivery.

Aircraft need spare parts, maintenance, repairs, engine overhauls, upgrades and life-extension work for years.

That means the economic relationship with the customer continues long after the original sale.

Few industrial businesses have customer relationships that can continue for several decades around the same physical asset.

That makes HAL's installed fleet extremely important.

The ₹2.55 lakh crore order book gives HAL unusual visibility

HAL's order book stood at approximately ₹2.55 lakh crore at the end of FY26.

That figure is many times larger than one year of revenue and gives the company strong visibility into future work.

During FY26 alone, HAL received more than ₹69,600 crore of manufacturing contracts and over ₹17,300 crore of repair and overhaul contracts.

The order book includes major programmes such as the additional Tejas Mk1A aircraft, helicopters, Dornier aircraft and other defence platforms.

This gives HAL a very different demand profile from a consumer manufacturer.

It does not need to build aircraft first and then hope customers appear.

Large parts of future production are already contracted.

That shifts the main challenge from demand creation to production execution.

HAL needs enough suppliers, engines, components, skilled labour and assembly capacity to convert the order book into actual deliveries.

India's defence forces remain HAL's main customer

HAL's business is still overwhelmingly tied to the Indian defence ecosystem.

The Indian Air Force, Army, Navy and other government-linked customers account for the majority of its manufacturing and maintenance revenue.

That concentration gives HAL a strong domestic position, particularly because many platforms are tied directly to India's defence-indigenisation strategy.

It also creates dependence on government procurement cycles.

Large orders can take years to move from development and approval to final contract and production.

Once awarded, however, these contracts can provide revenue visibility over long periods.

This is one reason HAL's business can be lumpy from year to year. A delay in one major platform or component can shift substantial revenue between financial periods.

Exports are growing, but remain small

HAL has been trying to expand outside India through aircraft exports, repair work and aerospace partnerships.

Export revenue reached roughly ₹501 crore in FY26, up from around ₹400 crore in the previous year.

That represents progress, but exports are still small compared with HAL's total revenue of more than ₹33,000 crore.

The domestic defence market therefore remains the core business.

Export programmes could become more important over time, particularly for helicopters, Hindustan-228 aircraft, components and maintenance services, but HAL has not yet built a large international revenue base.

For now, exports should be viewed as an additional growth opportunity rather than a central part of the business model.

Other income also supports HAL's profitability

HAL's profitability is helped by another feature of long-term defence contracting: large cash balances and customer advances.

Defence projects can involve milestone payments, advance payments and long production timelines. HAL can therefore hold significant cash before every contract is fully completed.

This generates interest and other income.

That income is not part of the core manufacturing or maintenance business, but it can still contribute meaningfully to overall profit.

This partly explains why HAL's profit margins can look stronger than those of many traditional heavy manufacturers.

The company benefits not only from its operating businesses but also from the financial income generated by its balance sheet.

Manufacturing could become a much larger share of revenue

HAL's current revenue mix is still dominated by repair and overhaul, but management expects that balance to shift.

Manufacturing revenue increased from about ₹7,957 crore in FY25 to ₹9,227 crore in FY26, even though some important programmes faced supply-chain delays.

As Tejas Mk1A, helicopter, trainer and engine orders move deeper into production, manufacturing could grow faster than maintenance.

HAL has indicated that the long-term mix could move closer to 50:50 between manufacturing and repair and overhaul.

That does not require the maintenance business to shrink.

Instead, new manufacturing can grow rapidly while the existing MRO business continues expanding alongside the installed fleet.

This is an important distinction because HAL could end up with two large engines working at the same time: one driven by new defence production and another driven by decades of lifecycle support.

Supply chains are the biggest near-term constraint

HAL has no shortage of contracted demand. The challenge is delivering against it.

Military aircraft depend on thousands of components, many of which come from specialised suppliers. An aircraft that is almost complete still cannot be delivered if a critical engine, avionics system or component is missing.

The Tejas Mk1A programme has shown how one supplier delay can affect a much larger production schedule.

This creates a bottleneck in HAL's economics.

The order book may already exist, factories may be ready and the customer may be waiting, but revenue recognition still depends on a completed and accepted aircraft.

HAL is therefore trying to expand capacity while also increasing local sourcing and developing a larger domestic supplier ecosystem.

If that execution improves, the large order book can translate into much faster manufacturing growth.

What really matters

HAL's business is strongest when viewed across the entire life of an aircraft rather than at the point of sale.

A Tejas fighter, Dhruv helicopter or aero-engine creates manufacturing revenue when it is produced, but it can also generate maintenance, overhaul, spare-parts and upgrade revenue for decades afterward.

That explains why repair and overhaul still produces more than twice as much revenue as manufacturing today.

At the same time, HAL is entering a much larger production cycle. The ₹2.55 lakh crore order book, led by programmes such as Tejas, helicopters and engines, gives the company years of contracted work.

The next phase depends on how quickly HAL can convert that order book into deliveries.

If supply-chain constraints ease and production ramps successfully, manufacturing can become a much larger share of revenue while the existing aircraft fleet continues generating recurring maintenance income.

That combination is what makes HAL's business model distinctive: new aircraft create immediate manufacturing revenue, but every aircraft delivered also expands the maintenance business that can keep earning for decades.
