Frigate Niteroi class



The Vosper Thornycroft Mk10 design was announced in 1970 comprising four ships to be built in the UK and two in Brazil. They were all equipped with SAM Sea Cat but F42/43 have a different layout (see photos in ship pages) with a second 114mm gun plus 2 pairs of MM38 Exocets whilest the rest used the Ikara antisubmarine rocket launcher instead. They were all upgraded between 1995/2005 with SAM Aspide as pictured. The last ship U27 is sligthly different and configured as a training vessel
