Design
These ships were built with the experience and the technology already developed for the previous Lupo class. The Maestrale were quite bigger and heavier, so they were slower, but still capable of around 32 knots. The ships have a large superstructure, with one large turret and only one funnel. There are two enclosed pyramid masts, one of which is quite low, the other much taller. The superstructure continues without interruption until the hangar, and is made, as usual, with light alloys.
The propulsion system is based on two gas-turbine LM-2500 and two diesel engines, in a Combined diesel and gas configuration, that make use of diesel for cruising and turbines for high speed. The only problem with this configuration, which is highly economical, is to make the diesel engines powerful enough to achieve sufficient cruising speed without overloading them, or assist them with a continuous use (at low, uneconomical power) of the turbines. In this case, the solution, already developed for the Lupo class ships, was successful. The ships have a maximum range of 5,000 nautical miles (9,300 km) at 15 knots (28 km/h).

Famous quotes containing the word design:
“Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.”
—Ralph Waldo Emerson (1803–1882)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
“The reason American cars don’t sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. That’s why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
