K-4 MISSILE

About:

• K-4 is one of the two underwater missiles that were being developed by DRDO. The other one is the over 700 kilometre strike range BO-5 missile.
  
  
• The missile has been tested several times earlier as part of developmental trials to validate different parameters.
  
  
• Once inducted, these missiles will be the mainstay of the Arihant class of indigenous ballistic missile nuclear submarines and will give India the stand-off capability to launch nuclear weapons submerged in Indian waters.
  
  
• INS Arihant, the first and only operational SSBN, is armed with K-15 Sagarika missiles with a range of 750 km.
