HAL’s Aftermarket Business Emerges as Defence Growth Engine
Hindustan Aeronautics Limited earns money not only by building military aircraft but also by looking after them afterward.
This includes repairs, spare parts, engine work and upgrades.
Military aircraft can be used for many years, so they need regular support.
Kotak Institutional Equities estimates that this support business has an order book worth about Rs 24,000 crore.
HAL’s support revenue is expected to increase to Rs 29,000 crore by FY31.
Older aircraft may be upgraded instead of replaced, creating more work for HAL.
The planned Super Sukhoi upgrade could become a particularly large opportunity.
New Indian aircraft such as the Tejas Mk1A, LCH and LUH could also create future maintenance demand.
However, HAL’s manufacturing business is expected to grow faster, which may reduce profit margins.
HAL’s Repair, Overhaul & Spares business accounted for about 62% of FY26 revenue, up from 49% in FY19.
Kotak Institutional Equities estimates HAL’s ROH, spares and upgrade order book at approximately Rs 24,000 crore in FY26.
ROH revenue is projected to rise from Rs 20,500 crore in FY26 to Rs 29,000 crore by FY31.
The Super Sukhoi upgrade programme could cover more than 80 aircraft initially and potentially exceed Rs 50,000 crore.
Manufacturing is expected to grow faster than aftermarket services, potentially reducing ROH’s revenue share and pressuring margins.
