The Nuclear testing series programme refers to an active military programme directed towards the development of techniques of experimenting nuclear forces and further investigations of the blast effects. The programme was suggested and idealized by Munir Ahmad Khan– chairman of Pakistan Atomic Energy Commission (PAEC)– as early as 1977.[1]
First subcritical tests were carried out in 1983 by the PAEC, codename as Kirana-I, continued until the 1990s under Prime Minister Benazir Bhutto.[1][2] Further claims of conducting subcritical tests at Kahuta were made in 1984 by KRL but were dismissed by the government. Due to amid tensions arisen with BJP-led government under Prime Minister Atal Vajpayee's decision of Pokhran-II– codename of India's nuclear tests in 1998.[3]
The PML government led by Prime Minister Nawaz Sharif authorized the programme jointly under PAEC and KRL, assisted by Corps of Engineers in 1998. There were six nuclear tests performed under this programme: codename: Chagai-I and Chagai-II. After the Prime Minister Atal Vajpayee paying a state visit to Pakistan to meet with Prime Minister Nawaz Sharif, both countries signed a nuclear testing control treaty, the Lahore Declaration in 1999.[4]
