Farkhor has seen a few Mi 8 but the current status is unknown. Ayni lease is still being negotiated.
So a threat does exist irrespective of what assets are deployed there. It would automatically be taken into any strategic planning, ignoring it may not be possible neither for military nor at government level.
Russian border troops were stationed along the Tajik–Afghan border until summer 2005. Since the September 11, 2001 attacks, French troops have been stationed at the Dushanbe Airport in support of air operations of NATO's International Security Assistance Force in Afghanistan. United States Army and Marine Corps personnel periodically visit Tajikistan to conduct joint training missions of up to several weeks duration. The Government of India rebuilt the Ayni Air Base, a military airport located 15 km southwest of Dushanbe, at a cost of $70 million, completing the repairs in September 2010.[40] It is now the main base of the Tajikistan air force. There have been talks with Russia concerning use of the Ayni facility,[41] and Russia continues to maintain a large base on the outskirts of Dushanbe.[42]
In 2010, there were concerns among Tajik officials that Islamic militarism in the east of the country was on the rise following the escape of 25 militants from a Tajik prison in August, an ambush that killed 28 Tajik soldiers in the Rasht Valley in September,[43] and another ambush in the valley in October that killed 30 soldiers,[44] followed by fighting outside Gharm that left 3 militants dead. To date the country's Interior Ministry asserts that the central government maintains full control over the country's east, and the military operation in the Rasht Valley was concluded in November 2010.[45] However, fighting erupted again in July 2012.[46] In 2015, Russia sent more troops to Tajikistan.[47]
In May 2015, Tajikistan's national security suffered a serious setback when Colonel Gulmurod Khalimov, commander of the special-purpose police unit (OMON) of the Interior Ministry, defected to the Islamic State.[48]

Ayni Air Force Base, also known as Gissar Air Base, is a military air base in Tajikistan, just 10 km west of the capital Dushanbe.[1]
During the Cold War era, Ayni served as a major military base of the Soviet Union. However, following Soviet withdrawal from Afghanistan, the base's infrastructure deteriorated significantly. Between 2002 and 2010, India spent nearly US$70 million to renovate the air base — the runway was extended to 3,200 meters and state-of-the-art navigational and air defense equipment were installed.[2][3] It was speculated by some media outlets that India was keen on establishing a military base in Ayni so as to gain a strategic foothold in Central Asia.[3]
In January 2011, Tajik Foreign Minister, Hamrohan Zarifi, officially launched negotiations with Russia to discuss possible deployment of Russian military at Ayni. Zarifi also ruled out deployment of Indian or American forces at Ayni.[4]
