Why warship interiors matter to diplomacy

Will Type 83 have wood panelling and a piano like some Russian warships?

Possibly modest versions, because warships also act as diplomatic embassies and need credible reception spaces.

Practical decoration is more likely than the lavish interiors associated with some Russian ships, though an upright piano and wood panelling remain possible. Such fittings are more than crew comforts. Warships host foreign officials and represent the country abroad during port visits. A purely austere and visibly shabby reception space would weaken that diplomatic function.
