Historical Background

World War II Origins

Established in 1940 by the Royal Navy, Sulur Air Force Base served as a critical airfield for Allied forces in Southeast Asia during World War II (military-history.fandom.com). Originally called RNAS Sulur, it functioned as a repair and transit base, later coming under the Royal Air Force (RAF) as part of the South East Asian Command (wikipedia.org). Well-equipped for its era, the base featured hangars, aircraft pens, fuel stations, and accommodations. The Royal Navy’s Fleet Air Arm operated the Royal Navy Air Yard (RNAY Sulur), focusing on the maintenance of aircraft such as Hellcats and Barracudas (globalsecurity.org).

Involvement in the Independence Movement

During the 1942 Quit India Movement, Sulur played a role in the independence struggle. On August 26, 1942, the base was set ablaze amid widespread protests, briefly halting operations. It was quickly restored due to its strategic importance, and by 1943, the Royal Indian Air Force (RIAF) began operations at Sulur, continuing until 1949 (military-history.fandom.com).

Post-Independence Transition

After India gained independence, the Indian Navy took over and established INS Hansa at Sulur, operating Hawker Sea Hawk aircraft (indiaairport.com). Following the liberation of Goa in 1961, INS Hansa relocated to Dabolim, and Sulur was transferred to the Indian Air Force in 1956. The IAF then established No. 5 Base Repair Depot (5 BRD) in 1959, transforming Sulur into a significant maintenance hub (globalsecurity.org).

Expansion and Modernization

The 1960s and 1970s saw significant infrastructure development, including new hangars and the commissioning of No. 33 Equipment Depot in 1967 (wikipedia.org). The base also supported civil aviation and hosted motorsport events (indiaairport.com). Sulur provided critical support during the 1971 Bangladesh Liberation War and the Indian Peace Keeping Force operations in Sri Lanka in 1987.

Contemporary Era

Since 1984, Sulur has been fully operated by the IAF and is now India’s second-largest airbase, covering over 1,000 acres (wikipedia.org). Notable units include:

No. 5 Base Repair Depot (5 BRD): Aircraft overhaul and calibration
No. 43 Wing: Operational support
IAF Squadron 33 "Himalayan Geese": Antonov An-32 airlifters
Helicopter Unit Squadron 109 "Knights": Mil Mi-8 helicopters
Sarang Helicopter Display Team: Aerobatic team flying HAL Dhruv helicopters (indiaairport.com)

The base features a 2,516-meter runway, advanced landing systems, and state-of-the-art communications (wikipedia.org).
