Heres and old excerpt from an old CF-18/CF-188 suggestion in which I commented about its weaponry and differences;
"The CF-18 was acquired to replace both the CF-101B in the interceptor role, as well as the CF-104 and CF-116A (CF-5A) in the strike role. They wanted to consolidate the combat jets as much as possible. In comparison to the US Hornet however, it still didn’t have quite the extensive list of weapon racks and weapons.
A couple non-visual changes between the CF-18A and F/A-18A’s was the Instrument Landing System instead of the Automated Carrier Landing System, ALQ-162 jammer, clearance for 480 gallon fuel tanks (vs. 330 gallon), and cold weather survival gear.
I’ve finally got an extensive and thorough list for weapons the CF-18 carried until it was modernized in 2003.
6x AIM-9L/M Sidewinders (Wingtips & outboard pylons with dual racks)
4x AIM-7F/M Sparrows (Fuselage recesses & outboard pylons)
4x AGM-65 Mavericks (Unknown version, likely F or G. inboard and outboard pylons)
152x 70mm CRV 7 rockets in 8x LAU-5003 pods (Dual racks on outboard and inboard pylons)
10x Mk-20 Rockeye cluster bombs (Dual racks on outboard, inboard, and centreline pylons)
10x BL-755 cluster bombs (Dual racks on outboard, inboard, and centreline pylons)
10x Mk.82 500 lb bombs (Dual racks on outboard, inboard, and centreline pylons)
9x Mk.83 1000 lb bombs (Dual racks on outboard and inboard pylons, single bomb on centreline pylon)
4x Mk.84 2000 lb bombs (outboard and inboard pylons)
4x GBU-12 500 lb laser guided bombs (outboard and inboard pylons)
4x GBU-16 1000 lb laser guided bombs (outboard and inboard pylons)
2x GBU-10 2000 lb laser guided bombs (outboard pylons)
2x GBU-24 2000 lb laser guided bombs (outboard pylons)
Originally the CF-18 came with no precision strike weapons, but Canada acquired laser guided bombs and Mavericks from the late 1990’s-2003 as well as beyond.
Missiles such as the AIM-120 and other guided weapons didnt come until after the 2003 modernization, which required new targeting systems and radar sets among other things.
The information comes from the Canadian Aviation and Space Musuem, trade registries between US and Canada on the sale of guided weapons, as well as the brochure for the F/A-18A and a weapons chart for the F/A-18C."
