In response to INS "Arihant", India's first nuclear submarine, the Pakistan Navy pushed forward a proposal to build its own nuclear submarine as a direct response to the Indian nuclear submarine program. Many military experts believe that Pakistan has the capability of building a nuclear submarine and is ready to build such a fleet. In February 2012, the Navy announced it would start work on the construction of a nuclear submarine to better meet the Indian Navy's nuclear threat. According to the Navy, the nuclear submarine is an ambitious project, and will be designed and built indigenously. However, the Navy stressed that "the project completion and trials would take anywhere from between 5 to 8 years to build the nuclear submarine after which Pakistan would join the list of countries that has a nuclear submarine."
