 Initially, the hand controller replaced the RIO's TARPS control panel, meaning a Tomcat configured for LANTIRN could not carry TARPS and the reverse, but eventually a workaround was later developed to allow a Tomcat to carry LANTIRN or TARPS as needed.An upgraded LANTIRN named "LANTIRN 40K" for operations up to was introduced in 2001, followed by Tomcat Tactical Targeting (T3) and Fast Tactical Imagery (FTI), to provide precise target coordinate determination and ability to transmit images in-flight.Tomcats also added the ability to carry the GBU-38 Joint Direct Attack Munition (JDAM) in 2003, giving it the option of a variety of LGB and GPS-guided weapons.
