Niderlandzkie kutry torpedowe typu T17 1934-1935 (16 jednostek)
Trzecia już generacja niderlandzkich
kutrów torpedowych. Jako pierwsza z nich, została wyposażona w wyrzutnie
torpedowe kalibru 533 mm.
Po osiem jednostek zbudowane zostało w
stoczniach A.F. Smulders w Schiedam i Willemsoord Werf w Den Helder.
Opis

Kadłub
O sporym, jak na kuter torpedowy
wydłużeniu.
Napęd
Trzy silniki diesla DAF po 780 KM
każdy.
Uzbrojenie
Kutry zostały wyposażone w:
- 1xIIx13,2/78
FN P1919, przy elewacji 45o donośność pociskiem 0,05 kg
wynosi 7000 m, a przy elewacji maksymalnej 85o donośność tym
samym pociskiem wynosi 4080 m;
- 2xIxwt
533 mm.
Inne
Na okręcikach zainstalowano dwie
radiostacje krótkiego zasięgu.
