After a change in the design, which shortened the vessel and gave her smaller torpedo stores than originally intended, this role was reduced.

The facilities on board and the size of the vessel ensured that academy cadets could get experience with navigation and command in addition to normal schooling.

[3] After several failed attempts to complete a sale by the FLO, in 2012 Horten and the by-then-demilitarised patrol boats were sold to British company CAS-Global Ltd on the basis that, although they were contracted to the Nigerian Maritime Administration and Safety Agency (NIMASA), they would be operating under UK flag and regulatory control.

[1] After delays, during which the patrol boats were delivered, in February 2014 the new owner brought Horten to Ramsgate, England, where she was detained by the Maritime and Coastguard Agency over registration and technical issues.

[3][7] Its final report was made in May 2016, confirming that the FLO was aware that the true end-user was Global West, not CAS-Global, but hid that from Government, and were not proactive in trying to prevent the British authorities allowing Horten to be delivered.

[9][10] In June 2015, the ship was transferred to Nigerian registration, in ownership of Molecular Power Systems Ltd., Lagos, which was associated with Global West.
