Does Singapore base aircraft abroad because it lacks space at home?
Short answerThe main purpose is dispersal, keeping a first strike from destroying too much of Singapore's air power at its home bases.
NotesA question suggests that Singapore keeps aircraft abroad because the island lacks room for enough bases, but space is not the main reason. Dispersal prevents a first strike from wiping out aircraft concentrated at home. A small state can use external access to create operational depth that geography does not provide.
