In October 1992, the Dutch Government ordered three Agusta-Bell AB412SP as a replacement for the remaining four
Eurocopter SE-3160 Alouette III
helicopters of the SAR Flight of the Royal Netherlands Air Force.
Deliveries of the Agusta Bell AB-412SP R-01 (s/n 25630), R-02 (s/n
25638) and R-03 (s/n 25641) started in 1993. Agusta Bell AB-412SP R-01
was handed over on 11 November 1993 and arrived on delivery at Leeuwarden Air Base
on 4 March 1994. The AB-412SP was used for Search and Rescue-tasks, including emergency
assistance for the Frisian Isles. This medevac-task meaned that the helicopter was used for
emergency transport of persons from the Isles to the hospitals on the mainland. For this work,
the helicopters were equipped with emergency floats and an hoist. In 1998, the SAR Flight was
renamed 303 squadron. On behalf of their yellow colour the helicopters received the nickname
"Tweety". On 1 January 2015, the Royal Netherlands Air Force took the three Agusta-Bell AB412SP
SAR helicopters out of service. On 15 January 2015, the 303 squadron was be officially disbanded. After the
three Agusta-Bell AB412SP helicopters were withdrawn from use they were offered for sale. The three helicopers
were sold to Peru where they are used for a SAR task. In June 2015, Agusta-Bell AB412SP s/n 25630 entered service
as HAL-460 with the Peruvian Navy / Marina de Guerra del Peru.
