In comparison to the Legacy Hornet, the Super Hornet is roughly 20% larger, 7,000 lb (3,200 kg) heavier at empty, and 15,000 lb (6,800 kg) heavier at maximum weight
The key distinction between the Boeing F/A-18 “Legacy” Hornet and the F/A-18 Super Hornet is shown in the amazing video in this post.
A twin-engine multirole fighter with carrier capability, the McDonnell Douglas Super Hornet was developed and made its first flight in 1995. It is based on the McDonnell Douglas F/A-18 Hornet. The larger and more modern F/A-18C and D Hornet derivatives are the single-seat F/A-18E and twin-seat F/A-18F.
A number of features, such as avionics, ejection seats, radar, weapons, mission computer software, and maintenance and operating procedures, are shared by the Hornet and Super Hornet. In comparison to the Legacy Hornet, the Super Hornet is roughly 20% larger, 7,000 lbs (3,200 kg) heavier at empty, and 15,000 lbs (6,800 kg) heavier at maximum weight. In comparison to the Legacy Hornet, the Super Hornet has 33% more internal fuel, a 41% increase in mission range, and a 50% increase in endurance.
The Super Hornet must have its catapult and arresting systems adjusted differently than the Legacy Hornet because of its higher weight. The Super Hornet is colloquially known as the “Rhino” to distinguish it from earlier Hornets in order to promote safe flight operations and avoid confusion in radio calls. (The McDonnell Douglas F-4 Phantom II, which was decommissioned from service in 1987, was originally known as the “Rhino.”)
Additionally, unlike the Legacy Hornet, the Super Hornet is built to be equipped with an aerial refueling system (ARS) or “buddy store” for the refueling of other aircraft, filling the tactical airborne tanker role that the U.S. Navy had lost with the retirement of the KA-6D Intruder and Lockheed S-3B Viking tankers.
