If the delivery of Tejas MK1A continues to face delays and Tejas MK2 enters serial production by 2028, especially with the local manufacturing of GE F414 engine in India, IAF might consider capping the MK1A order at 83 units and instead procure additional Tejas MK2s. However, this presents a logistical challenge — the hardened shelters built for the MiG-21 can only accommodate the smaller Tejas MK1A. Inducting the larger Tejas MK2 would require constructing new hardened shelters, which would significantly increase costs.
