As per sources a squadron comprises of 12-24 aircrcaftOk. Double standards again to your neighbors I see.
The first Tejas IAF unit, No. 45 Squadron IAF Flying Daggers was formed on 1 July 2016 with two aircraft. It was commissioned by Indian Defence Minister no less. Indian and Foreign media was present. Including times.
Do not confuse yourself with FOC and operation.
