Visby corvettes in latest version

At the very beginning it was thought that there would be 10 ships – two versions with different specialties. Circumstances resulted in five ships with all functions. They all had to fit on 72-meter vessels.

In 2012 FMV delivered two corvettes of Visby class to the Swedish Armed Forces. This means that there are now two Visby corvettes which can hunt submarines with torpedoes, depth charges and sonar. They can both deploy and clear mines, and fire anti-ship missiles. They also have an airport function for takeoff and landing helicopters.

All five Visby corvettes have advanced surveillance radar and a 57-millimeter cannon that can hunt and defeat both sea and air targets.

Anders Nilsson, who is project manager for the Visby corvettes, notes that there were delays in the early stages of the project, but that FMV now is in complete agreement with the timetable set up in agreement with the Swedish Armed Forces.

"It is of course, incredibly satisfying that two of the five vessels now have all the functionality requested by the customer.

The first missile firing from a ship

Right up to delivery the project team worked on getting all systems in place. Among other things, the vessels participated in joint exercises with other units of the Swedish Armed Forces, where the Visby-class Corvettes got their airport operation certified. Another important milestone was the verification of the qualifying test firing of anti-ship missiles from a vessel.

"Of course it was a bit tense. We had tested everything over and over again, but there were many things that were supposed to happen not only in a short time, but also for the first time", says Anders Nilsson. "Compared to a test site on land which is completely still, a ship that rolls and heaves is a very different thing."

But the test shots went well and Anders Nilsson concludes that "FMV has managed to integrate the powerful weapon onto a ship with requirements for very low signatures something that is not a given, considering the forces that the missile unleashes.

There is no equivalent

It is difficult to find ships with the same characteristics as the Visby corvettes. They are multi-purpose vessels with the ability to operate both below and above water, plus they also have very low signatures, making them difficult to detect on radar and other sensors, both above and below water.

During the project several major technology barriers have been broken through. Multifunctional ability is one. Stealth characteristics with low signatures, and with the hull in carbon fiber as a key part,is another. Development at the brink of what is technically possible is either very expensive or rather protracted. The Visby Project allowed for the time necessary to find new solutions.

But that is all in the past. Work is now underway to upgrade the remaining three corvettes, and in 2014 FMV will have delivered all corvettes of the Visby class in version 5.
