Ladakh became a UT on October 31 after the central government on August 5 last year revoked the special status given to the erstwhile state of Jammu and Kashmir.
The CISF, the 162,000 personnel strong paramilitary, is designated as the national
civil aviation security force.
A formal induction ceremony was held at the airport that was attended by CISF
Director General (DG) Rajesh Ranjan, its special DG (airports) M A Ganapathy and airport director Sonam Norbu among others.
Norbu handed over a ceremonial key of the airport to CISF Deputy Commandant and chief airport security officer Sanket Gaikwar, the officer said.
DG Ranjan, the CISF officer said, "emphasised that coordinated efforts are to be made by all government agencies and stakeholders to ensure security of the Leh
Ranjan also asked his personnel to ensure "zero error" security at the facility.
On Tuesday, he had inaugurated barracks for the CISF personnel who will be posted to guard the facility and he reviewed other operational systems of the airport.
Air India, Vistara, GoAir and SpiceJet operate commercial passenger flights between Leh
and Delhi. Commercial operations began at this "tourist intensive" airport in 1978.
A new passenger terminal is being built here at a cost of Rs 480 crore and is expected to be completed by September next year.
The CISF contingent will provide 24x7 armed cover to the facility and will check passengers while approaching the facility, at the terminal gates followed by comprehensive checks and body frisking ahead of boarding a flight.
The troops are armed with assault rifles like the AK series and the INSAS, and will man the airport perimeter from watch towers erected at vantage positions.
The force has a special aviation security group (ASG) to provide counter-terror cover to the airports and it has similarly taken over the Srinagar and Jammu (Jammu and Kashmir) international airports in February and March respectively.
Handover of the three strategically important and sensitive airports of Srinagar, Jammu and Leh to the CISF was expedited after Jammu and Kashmir Police officer Davinder Singh was arrested from Srinagar in January while he was allegedly ferrying three Hizbul Mujahideen terrorists to Chandigarh.
The Union government has said that CISF will be the only civil airports guarding force and all such facilities in the country will be gradually brought under its command to bolster aviation security and tighten anti-terror and anti-hijack protocols.
