Project history

Colonial high-endurance sloops. The order was originally given out in 1931 to OTO (offered 2100t ships), but in connection with traditionally strong British effect and on financial motives in the same year the order was transferred to Hawthorn Leslie. The design was developed under effect of French Bougainville aviso. Officially Afonso de Albuquerque and Bartolomeu Dias were rated as 1st class avisos. Machinery included two 3-drum Yarrow boilers and Parsons geared turbines. Originally ships could carry a seaplane, but aviation equipment was removed soon after commission.

Modernizations

1935, both: - seaplane

1944, both: - 4 x 1 - 40/39; + 8 x 1 - 20/70 Oerlikon Mk II/IV, 4 DCT, presumably sonar

1950s, both: + radar
