Yesterday’s flight was an early flight, due to an ultra light airfield being close by & I didn’t want to cause any issues, keeping a keen eye + ear out looking & listening for any aircraft in case they came in? I was also listening to air channels 118.925 + 122.255! This is UB-122 visible near Hublebee Creek which is near the Isle of Grain in Kent. Marine archaeologist Mark Dunkley said that the U-boat had been there since 1921 & perhaps a storm might have parted it from its tow while it was being taken for scrapping. The diesel engines were removed from UB-122 & were reused in a cement factory at Halling, Kent. It’s the only known complete U-boat that can be seen in UK’s tidal waters. UB-122 was a type UB III German submarine that could carry 10 torpedoes, 3 officers & 31 crewmen. It was commissioned on 4th March 1918 & surrendered to the Royal Navy on 24th November 1918. UB-122 had the speed of 25.7 kmph or 13.9 knots. The sub had a displacement (weight) of 512 tons while surfaced & 643 tons while submerged. It was 55.85 meter long, 5.8 meter wide & the distance from waterline to its keel was 3.72 meter. It could dive to 150 feet in 30 seconds. Though UB-122 made two patrols during WWI, it failed to sink any targets.
