availability. Sif went on to become one of the ICG most successful aircraft to date. During its 22-year career it took part in several high profile rescue operations around Iceland and is credited to have been involved in the rescue of around 250 lives. In 1995, the ICG received a second specialised SAR helicopter when it bought an Aérospatiale AS-332L1 Super Puma which was given the name Líf. The new helicopter continued on the success of Sif and gained national fame when it rescued 39 sailors in three separate incidents during a six-day period in March 1997. As a response to the withdrawal of the Iceland Defense Force in 2006, the Coast Guard expanded its helicopters to four in 2007. That number was later reduced to three and as of 2022, it operates three Airbus Helicopters H225 helicopters named Gná, Gróa and Eir. The Coast Guard also operates a single Bombardier DHC-8-Q314, registered as TF-SIF, modified for maritime surveillance and reconnaissance. This plane has been extensively modified by FIELD to carry a modern Mission Management System and suite of surveillance sensors, air operable door and communications/navigation equipment. It is occasionally also used for surveillance of volcanic eruptions, such as the 2010 eruptions of Eyjafjallajökull.
