Here are some excerpts of Pak Navy Chief's recent interview with DefenseNews:
Q. One of the most high-profile acquisition programs of your predecessors tenure was the next-generation submarine. Can you expand on reports of a Chinese submarine design being selected, and comment on whether the HDW Type-214 may still see service with Pakistan as a replacement for the Agosta-70s?
A. Submarines all along have been our main strength and at the heart of our naval strategy of offensive sea denial. Over the years, the strength of our submarines has dwindled due to aging. Our primary consideration is to acquire modern and potent submarines. All options, including submarines of the West, as well as China, are under deliberation, though no decision has been taken as yet.
Q. Long-standing plans include the expansion of the shipbuilding industry but also to diversify construction locations away from Karachi to places like Gwadar and Ormara. Where do these plans stand?
A. Our long-term plan is to have two major shipbuilding and repair yards at Port Bin Qasim in the east and Gwadar in the west. In addition, we have a strategic plan to develop this rich but hitherto untapped segment of our maritime sector. To realize the same, we have a high-level shipbuilding task force formed under the aegis of [the Ministry of Defence Production].
Q. How do you plan to replace the P-3C Orions destroyed by terrorists last year? And what else can we expect from the Navys maritime patrol aircraft procurement efforts? Have you examined any Chinese options, such as the H-6K or Y-8Q? And is any thought being given to replacing your elderly Westland Sea King helicopters yet?
A. Despite the loss of two P-3Cs during the unfortunate attack on [Pakistan Naval Station] Mehran last year, our maritime surveillance capability remains intact and we can well manage our operational requirements. Nevertheless, we have initiated the process for the replacement of the destroyed aircraft from the U.S. and remain hopeful of a positive outcome. You must appreciate that the P-3C is designed for long-range surveillance. Deploying this aircraft continuously for routine surveillance in peacetime is not only uneconomical, it actually amounts to its underutilization. We are thus maintaining smaller and cheaper maritime patrol aircraft i.e., FK-27S which fulfills our day-to-day operational needs. Apart from that, we are considering a range of other surveillance aircraft, including Chinese options.
With regard to our Sea King helos, we have signed the Mid Life Upgrade Program, under which a new and modern avionics suite and sensors will be fitted onboard, making them a more potent and capable aerial platform.
Q. The effectiveness of the small number of Exocet-equipped anti-ship strike Mirage-5 aircraft is now surely questionable. What do you intend to replace them with? And is there a case for having these Pakistan Air Force aircraft under naval control?
A. PAF Mirage aircraft equipped with missiles are effective [anti-shipping strike] platforms. The PN and PAF have put in place an efficient mechanism for their optimum deployment, which is why we dont feel the need to place them under PN control. There are plans to replace the systems which become obsolete or are no longer operationally effective.
Q. Later this decade, you will face an Indian nuclear-powered, nuclear-armed ballistic submarine that threatens the current strategic balance in South Asia. How do you intend to respond?
A. The strategic dimension of Indias naval buildup is a cause of concern not only for us but for the entire Indian Ocean region. I feel nuclearization of the Indian Ocean does not augur well for peace and stability in the region. We are mindful of this development and taking necessary measures to restore the strategic balance.
