Spitbank Fort is a sea fort built as a result of the 1859 Royal Commission.
Its main purpose was as a further line of defence for ships that made it past the two main forts. It is 49.4 metres (162 ft) in diameter across at its base, with one floor and a basement and armour plating only on the seaward side. It was originally planned to have been armed with nine 10" 18-ton rifled muzzle loader (RML) guns on the seaward side, and six 7" seven-ton RML guns on the landward side.
However, by the time of completion the plan had changed so that the seaward side received nine 12.5-inch muzzle-loading (RML) guns. From 1884 more modern 12-inch breechloading guns were installed and these were in service until after World War I.
The fort is one of four built as part of the Palmerston Forts constructions.
Located in the Solent, near Portsmouth, England, and is now in private ownership following its sale after a period as a luxury hotel.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 11/07/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
I’ve easily managed two rounds trips to the fort on one battery. I was flying the Mavic Pro that has a shorter total flight time, so you have no worries with the Mini 3 Pro for a single trip.
Edit: Just looked back at a typical flight to the fort. Probably more relevant than battery info, the flight was just under 9 mins which included a couple of mins flying around the fort. Just a steady 30kph/18mph on the way out and back.
Not yet, but it would be interesting. Needs a calm-ish day, but it’s less than a 15 minute round trip.
Theoretically, all three forts can be done in one flight … if you have a drone that manages about 21 minutes on a battery. Theoretically, my Mavic Pro can do this … but I’d need to check if any of my aging batteries can still manage that long.
