Quick answer
Juliett represents J. Its single-letter signal warns that the vessel is burning with dangerous cargo aboard and others must stay well clear, or that dangerous cargo is leaking. Omitting the leakage alternative gives an incomplete meaning. See NGA Publication 102, Single Letter Signals.
| Feature | Description |
|---|---|
| Letter and spelling | J; Juliett, with two final t letters. |
| Pronunciation | JEW LEE ETT in the Code's letter spelling table. |
| Pattern | Horizontal blue, white and blue bands, from top to bottom. |
| Overall proportions | No universal hoist-to-fly ratio established here; a reference illustration is not a dimensioned manufacturing standard. |
| Colour specification | Blue and white identify the pattern. No authoritative textile colour values or digital colour equivalents are established here. |
Construction and reproduction
The Code’s flag chart supports identification, but this record does not derive exact band widths, overall dimensions or colour coordinates from artwork. A manufacturing specification must separately establish those details. No documented common-manufacture ratio is asserted. Screen colours are approximations; any newly dimensioned drawing would be an editorial reconstruction unless supported by a construction standard.
Historical context and present status
Resolution A.80(IV), adopted on 27 September 1965, adopted the revised International Code of Signals. That is a revision date for the Code, not evidence of the first appearance of Juliett’s flag design. The resolution proposed 1 January 1968 for implementation subject to specified international radio coordination conditions; it should not be presented as an unconditional commencement date. See Resolution A.80(IV).
The IMO publication record states that the Code has not been amended since its fourth edition and that the 2005 edition and the later edition described there are equally valid. Juliett is treated here as a current signal, rather than a retired historical flag.
