mechanisms. In 1991, Canada committed 26 CF-18s to the Gulf War, based in Qatar. These aircraft primarily provided Combat Air Patrol duties, although, late in the air war, began to perform air strikes on Iraqi ground targets. On 30 January 1991, two CF-18s on CAP detected and attacked an Iraqi TNC-45 patrol boat. The vessel was repeatedly strafed and damaged by 20mm cannon fire, but an attempt to sink the ship with an air-to-air missile failed. The ship was subsequently sunk by American aircraft, but the Canadian CF-18s received partial credit for its destruction. In June 1999, 18 CF-18s were deployed to Aviano AB, Italy, where they participated in both the air-to-ground and air-to-air roles in the former Yugoslavia. 62 CF-18A and 18 CF-18B aircraft took part in the Incremental Modernization Project which was completed in two phases. The program was launched in 2001 and the last updated aircraft was delivered in March 2010. The aims were to improve air-to-air and air-to-ground combat abilities, upgrade sensors and the defensive suite, and replace the datalinks and communications systems on board the CF-18 from the F/A-18A and F/A-18B standard to the current F/A-18C and F/A-18D standard. In July 2010 the Canadian government announced plans to replace the remaining CF-18 fleet with 65 F-35 Lightning IIs, with deliveries scheduled to start in 2016. In November 2016, Canada announced plans to buy 18 Super Hornets as an interim solution while reviewing its F-35 order. The plan for Super Hornets was later, in October 2017, put on hold due to a trade conflict with the United States over the Bombardier C-Series. Instead, Canada was seeking to purchase surplus Hornets from Australia or Kuwait. Canada has since acquired 25 ex-Australian F/A-18A/Bs, the first two of which were delivered in February 2019. 18 of these airframes will be introduced into active service with the remaining 7 to be used for spare parts and testing. Finland The Finnish Air Force ordered 64 F-18C/Ds (57 C models, seven D models) in 1992. All F-18D were built at St. Louis, and then all F-18C were assembled in Finland. Delivery of the aircraft started in November 1995 and ended in August 2000. The Hornet replaced the MiG-21bis and Saab 35 Draken in Finnish service. The Finnish Hornets were initially to be used only for air defense, hence the F-18 designation. The F-18C includes the ASPJ (Airborne Self-Protection Jammer) jamming pod ALQ-165.
