Okręt hydrograficzny typu Adriatyk 1934 (1 szt.)

Okręt hydrograficzny typu Adriatyk 1934 (1 szt.)

Do kompletu posiadanych już oceanicznych okrętów hydrograficznych typu Pacyfik, dodaję jeszcze jeden. Z uwagi na mający miejsce w ostatnich latach rozrost naszych posiadłości zamorskich, uznałem to za konieczne. Teraz każdy z trzech okrętów będzie obsługiwał ocean zgodnie ze swoją nazwą; czyli Atlantyk Atlantycki, Pacyfik Spokojny, a Adriatyk… Indyjski :).

Bardzo dobre właściwości morskie, wielki zasięg i autonomiczność, symboliczne uzbrojenie; cóż jeszcze można o tych jednostkach napisać?  Może to, że mimo „nikczemnego” znaczenia tego okrętu, jego sylwetka mi się bardzo podoba.
