Upgrading of missile gunboats
1986 to 1988

In the 1980s, the Missile Gunboats (MGBs) were equipped with long-range, hard-hitting Harpoon missiles, and an Action Information System (AIS) that allowed the MGBs to track and display other vessels. Together with other system upgrades, the MGBs were able to share a common tactical picture at sea, which tremendously increased the MGBs' ability to fight coherently as a force.
Warriors of the deep
Mid-1980s

In the mid-1980s, the Naval Diving Unit moved beyond a support role to include combat diving and mine clearance operations. Naval divers were sent for overseas courses, such as the elite Navy SEAL course. A new two-compartment walk-in hyperbaric chamber was commissioned at the Naval Diving Unit in 1984. It was Singapore's main centre for treating decompression sickness.
New strike capability
1990

With Singapore's prosperity increasingly dependent on maritime trade, the RSN saw an expansion of her mission beyond coastal duties to include ensuring the safety and openness of our sea lines of communication (SLOCs). The Navy was able to carry out this expansion in duties and operations with the Victory-class missile corvettes (MCVs), which are equipped with a complete suite of three-dimensional strike warfare capabilities. The first MCV RSS Victory was commissioned this year and introduced anti-submarine capabilities into the RSN.
