Abstract:
The Indian Ocean is rapidly surpassing both the Atlantic and Pacific Oceans as the world’s busiest
and most critical trade corridor, triggering several dramatic changes in the region. With the growth in
legitimate international commerce in the maritime domain, escalation of criminal activities has also
proliferated. Human and drug smuggling, weapons, and other contraband, as well as piracy and armed
robberies against vessels, pose a serious threat to maritime security. The existing level of protection
given to the maritime assets and the sealines is grossly inadequate.
The Sri Lanka Navy (SLN) is conducting surveillance in brown water ranging from 50 Nm to 100 Nm
as and when required. Due to the limited number of blue water ships, SLN’s capacity is restricted to
continuous surveillance. All ships that sail on the international waters are fitted with the Automatic
Identification System (AIS) which emanates position, identity, course and speed over ground, heading
and rate of turn as well as navigational status and the destination of the ship. The information received
is easily plotted on an electronic chart display system which has the capability of identifying rogue
ships in the Exclusive Economic Zone, but the existing shore based sensors’ are restricted with poor
coverage due to range. To overcome this limitation surveillance aircraft can be fitted with the AIS to
cover a larger sea area.
The objective of this research study is to establish the possibility of using indigenous mechanisms to
upgrade the capabilities of the Sri Lanka Air Force’s (SLAF’s) existing Unmanned Aerial Vehicles
(UAV) with minimum capital commitment.
The research team has carried out in-depth analysis of the existing reconnaissance procedure of SLN.
A number of interviews have been conducted with senior Naval officers who are directly involved in
the operation and had identified its limitations. There is a possibility of fixing an airborne AIS system
to available UAV’s and the engine power/aircraft weight ratios have been calculated for the
modification. It has been determined to position the available Ground Data Terminal on a SLN ship.
This will facilitate the UAV to extend its range. As follow up to this study, the team intends studying
the possibility of linking up the UAV Uplink/Datalink with a satellite to gain more range since Sri
Lanka will have one of her own very soon. The time is ripe to integrate the SLAF’s and SLN’s
capabilities to strengthen surveillance mechanisms, effectively arresting the emerging transnational
threats in the Maritime domain.
