The Arabian Sea has become the nucleus of international maritime operations, since the bulk of petroleum products from the Middle East, and trade goods of myriad nationalities ply these waters. Pakistans strategic location made it imperative to contribute towards maritime cooperation since the region has been engulfed in the threat of terrorism and piracy. Cognisant of the fact that no single navy can ensure the uninterrupted supply of petroleum to meet the global energy needs, Pakistan Navy (PN) has developed the concept of Aman (peace) series of exercises. These exercises encompass professional and social activities in harbour and at sea designed to promote coordination, interoperability and harmony among international navies. The concept incorporates the complete gamut of manoeuvres to test full operational limits, while undertaking strategies and tactics designed to counter the major threats to maritime security. The first of the series was conducted in 2007, followed by 2009 and now Aman-11, which was executed from March 8 to 12, 2011; subsequently building on lessons learnt from each. The defence planners will evolve lessons in time, but the general lessons that emerged from Aman-11 are presented here. This years exercise was designed to develop and improve tactics and techniques against maritime terrorism. Thus, it was based on offensive and defensive operations to protect the economic activities at sea. The major threats to maritime security comprise the use of force against the sovereignty, territorial integrity or political independence of a state; terrorist acts against shipping, offshore installations and other maritime interests; illegal transport of weapons of mass destruction, unlawful acts; piracy and armed robbery at sea; transactional organised crime like human trafficking, smuggling of narcotics, drugs and arms; threats to resource security such as illegal, unregulated and unreported fishing; and environmental threats e.g. major pollution incidents, illegal dumping. The planners of Aman-11 must be credited for focusing on objectives like the display of united resolve against terrorism and crimes in maritime domain; contributing towards regional peace and stability and enhancing interoperability between regional navies thereby acting as a bridge between the regions. Furthermore, the concept of the exercise revolved around the provision of a common forum for information sharing, mutual understanding and identifying areas of common interest; and the development and execution of response tactics, techniques and procedures against asymmetric and traditional threats during sea phase of the exercise. The 12 navies that participated with their naval assets such as ships, aircraft and marines and the 31 navies, who contributed as observers, gelled into one cohesive force to achieve maritime security management by transcending national boundaries and regional jurisdiction. It is heartening to note that Aman-11 blended theory and practice to achieve its ends of combating contemporary challenges in maritime security. For the theoretical brain storming session, the National Centre for Maritime Policy Research organised and hosted an International Maritime Conference in which a diverse group of scholars presented papers on the theme of 'Maritime Security Management - Contemporary challenges and need for global cooperation. The international conference was aimed at identifying the untapped economic, political and social areas of cooperation among the littoral states promoting the need of creating maritime awareness in the region. The planners of the exercise must take solace in the fact that they managed to promote and create understanding towards reassessing their working direction, decision making and enhancing their overall maritime vision. It will not be out of place to mention that Aman-11 identified new opportunities emerging from the ocean for problem solving, conflict resolution and took cognisance of the emerging dangers and challenges being faced and their effects on littoral states mindset and vision. The participating navies and observers of this multination exercise will benefit immensely from the evolved measures and steps towards a collective approach to dealing with maritime threat. Our navy deserves kudos for its endeavour because in the current times, when Pakistan had become nearly isolated, having the lost the opportunity to host the Cricket World Cup, and other sports, business and trade teams avoiding Pakistan due to terror threats; for the PN to host 40 navies, share cultural, sports and operational activities with no hitch is a major achievement.
