Yiziphi izikhali ezazisetshenziswa emkhunjini ongaphansi kwamanzi i-U-3030?
Context:Isikebhe sangaphansi kwamanzi sasinesivinini esiphezulu esingu-15.6 knots (28.9 km/h; 18.0 mph) kanye nesivinini esiphansi kwamanzi esingu-17.2 knots (31.9 km/h; 19.8 mph). Lapho isebenza ngezimoto ezithule isikebhe singasebenza ngejubane lama-knot angu-6.1 (11.3 km/h; 7.0 mph). Lapho isicwilisiwe, isikebhe sasingasebenza ngama-5 knots (9.3 km/h; 5.8 mph) ama-340 nautical miles (630 km; 390 mi); lapho ivela, yayingahamba ama-15,500 nautical miles (28,700 km; 17,800 mi) ngama-10 knots (19 km/h; 12 mph). I-U-3030 yayihlomile ngamashubhu ayisithupha e-torpedo angu-53.3 cm (21.0 in) emgodini kanye nezibhamu ezine ezi-2 cm (0.79 in) C/30 eziphikisana nezindiza. Yayikwazi ukuthwala ama-torpedo angamashumi amabili nantathu noma ama-torpedo ayishumi nesikhombisa kanye nezimayini eziyishumi nambili. Lolu hlelo lwalunamaphoyisa amahlanu namadoda angamashumi amahlanu nambili.
I-U-3030 yayingathwala ama-torpedo angamashumi amabili nantathu noma ama-torpedo ayishumi nesikhombisa nemayini eyishumi nambili.
