3 - 381/44 Zalinsky pneumatic guns, 3 x 1 - 47/40 Hotchkiss Mk I
Authorized under the Act of 3.8.1886 as a 'dynamite-gun cruiser'; a second such ship authorized under the Act of 2.3.1889 was never built. The 381mm Zalinsky pneumatic gun was 16.8m long and the full calibre shell weighed 445kg with a 227kg dynamite warhead. The range was 1500-1600m, but three times this could be reached with sub-calibre shells. In Vesuvius the guns were fixed at 18° elevation and trained by moving ship. A total of 30 shells was carried.
CT was protected by 25mm plating.
1898: - 3 - 381/44; + TTs
She bombarded Santiago in 1898 but accuracy was very poor, and the pneumatic guns were later removed, and Vesuvius used as an experimental torpedo vessel.
