The ships operate through a multi-diesel propulsion scheme consisting of 2 x Grandi Motori Trieste BL-230.16 marine diesels coupled with 3 x Isotta-Fraschini ID 36SS6V diesel generators driving power to 2 x Shafts under stern. There is also a single Isotta-Fraschini VM-V613oT unit for emergency power. The relatively compact warship, therefore, makes headway at speeds reaching 21 knots and ranges out to 3,300 nautical miles.
Dimensions include a running length of 261.9 feet with a beam of 38.8 feet and a draught of 11.9 feet. Displacement under standard loads reaches 1,130 tons and 1,500 tons under full loads.
The class is outfitted with the SMA SPN-748(V)2 navigational aid, the AESN SPS-702(v)2 surface-search radar suite, the AESN SPG-70 (RTN-10X) Fire-Control (FC) radar unit and the GEM Elettronica Gemeni-DB navigational radar. A complete Electronic Warfare (EW) kit is also carried.
Armament is 1 x 76mm /62 caliber OTO-Melara Allagarto turreted main deck gun backed by 2 x OTO-Melara 25mm /80 caliber secondary guns. Beyond this the crew can operate up to 2 x 7.62mm MG42/59 general purpose machine guns against extremely-close-ranged threats approaching the ship.
Aboard is a crew of 60 personnel including six officer-level candidates. Onboard stores allow the ships to operate for up to 35 days before requiring some sort of resupply.
From 2014 onward, the class received a few modern installations centered on navigation and radar.
The Italian Navy currently (2018) operates three distinct patrol classes: Comandanti-class, Sirio-class and Cassiopea-class collectively numbering ten ships.
