Exercises Since its formation, the FPDA has conducted multilateral military exercises involving all five member states with operational command alternating between Singapore and Malaysia. These began as intermittent Air Defence Exercises (ADEX) in the 1970s before land and sea components were added in the 1980s. They have since become yearly fixtures and have grown in complexity, combining air, sea and land components to address both conventional and non-conventional threats. Whilst most exercises take place off the coast of Malaysia and Singapore, they have also extended into the South China Sea. Non-FPDA representatives are often invited to observe the drills. Examples of FPDA exercises include: Exercise Bersatu Lima – The first major exercise held in 1972. Exercise Platypus – The first land-based FPDA exercise which was held in Australia in 1981. Exercise Starfish – One of the first FPDA naval exercises, inaugurated in 1981. It has been replaced by Exercise Bersama Lima. Exercise Suman Warrior – A land-based exercise which originated in the 1990s and takes place in Australia and New Zealand. Exercise Flying Fish – The first combined air, sea and land exercise which was first held in 1997. With 39 warships and 160 combat aircraft, the inaugural exercise in 1997 was one of the largest to date and took place over 13 days. Exercise Bersama Padu – The name of this exercise translates to "Together United" in Malay.
