Fourth Substitute Pennant
Fourth Substitute Pennant Picture

International Code of Signals – Nautical pennant used by ships at sea and the U.S. Navy. This short pennant is described as red with a small yellow square (1/3 size of the hoist edge) and centered at the hoist edge. This pennant is known as the fourth substitute or replacement.


Pennant Code Meaning

Substitute for the fourth flag in this hoist or Absence of commanding officer (Inport).

The use of substitutes is to enable the same signal flag, either alphabetical flag or numeral pennant, to be repeated one or more times in the same group, in case only one set of flags is carried on board. The fourth substitute always repeats the fourth signal flag of that class of flags which immediately precedes the substitute.
