Quick answer
Foxtrot is the flag for F in the International Code of Signals. It has a red diamond on a white field. Used as a single-letter signal, it means “I am disabled; communicate with me.” The design and meaning appear together in the New Zealand Nautical Almanac 2025–26.

Construction notes and evidence limits
The almanac chart supports recognition of the red diamond on white. It is not used here to derive exact diamond dimensions, edge clearances or fabric proportions. A measured illustration would establish the geometry of that illustration, not a universal manufacturing specification.
No common-manufacture ratio is asserted without a documented supplier or procurement specification. Screen colours should be identified as approximations unless supported by an authoritative digital standard. Any newly drawn construction would be an editorial reconstruction unless checked against a dimensioned official source.
Code history
The preface to NGA Publication 102 records adoption of the revised Code by IMCO in 1965 and its effective date of 1 April 1969. The consulted United States edition is marked 1969 Edition (Revised 2020). These dates describe the Code and publication, not proven dates for the first appearance of Foxtrot’s design or meaning.
Foxtrot also appears in the New Zealand Nautical Almanac 2025–26. This supports its treatment as a contemporary maritime code flag; a separate design-origin date has not been established.
