Which of the following missiles was NOT developed under the flagship Integrated Guided Missile Development Programme (IGMDP) conceived by Dr. A. P. J. Abdul Kalam?
The IGMDP program (1982-2008) developed five physical missiles under the acronym PATNA: Prithvi, Agni, Trishul, Nag, and Akash. BrahMos was developed as a separate joint venture with Russia. [Memory Trick: Remember PATNA: 'P'-rithvi, 'A'-gni, 'T'-rishul, 'N'-ag, 'A'-kash, which excludes 'BrahMos'.]
