Australian radar production could include refinements that were harder to accommodate in British or American production runs numbering hundreds of sets. Small batches allowed more complicated improvements without conflicting with the same demand for mass output. That approach made sense when the rate of equipment production matched a smaller shipbuilding program. Operational need also influenced the main gun: corvettes on northern Australian routes received a 4-inch gun early or were re-equipped when one became available. It was considered better for anti-aircraft work than the 12-pounder.

Small radar batches and northern routes shaped equipment choices
Australian radar refinements reflected small production runs, while greater air-attack risk on northern routes encouraged fitting the 4-inch gun.
