Recently made this, I have written some stuff about the F/A-18's ingenious rudder techniques which make it very stable to fly...
When the F/A-18 was designed, McDonnell-Douglas and Northrop forgot to consider ground effect. This meant that they did not consider that the lift curve of the wing will be reduced and since the tail is also quite low to the ground, it will also be affected by this.
When they did the first flight and later flight testing, it was noticed promptly as the plane simply refused to takeoff at the speed they calculated and gave to the pilots.
At the end, not wanting to redo the whole wing geometry just for better takeoff performance, they made a fix which involved the twin rudders doing a "toe-in" movement. As in they both point inwards.
This was not only required during takeoff but also in-flight. So they had to create a rudder scheduler which reacted instantly with AoA rise to coordinate a rudder toe-in or toe-out to provide positive longitudinal stability.
Without this, at high AoA the plane was fighting the pilot to pitch up even higher or
The fix was simple enough but uncovered a series of fixes that were unnoticed while initially developing the plane. This meant the entire FCS was revalidated.. It was incredibly expensive and added complexity.
The pitching movement coefficient tells the direction of the pitching tendency.

U.S. Air Force Reveals Plans For VTOL Bomber Prototype | Aviation Week
U.S. Air Force seeks a reusable rocket-powered VTOL strike aircraft prototype for future high-speed bomber missions.

The New Frontier Aerospace hypersonic aircraft takes off vertically, much like a rocket without stages. The aircraft then lands vertically where it can then be refueled for another flight.

RENO, Nevada—The U.S. Navy is developing and currently flight testing a new long-range air-to-air missile that will far exceed the capabilities of the current AIM-120 and likely the recently disclosed AIM-174B as well.
The new AIM-424 “Malice” air-to-air missile is being developed for the F/A-18, the F-35 and F/A-XX. The missile was announced at the Tailhook Symposium here Aug. 22.
Specifics of the two-stage missile are classified and the Navy did not disclose the company producing the weapon. Imagery appears similar to the AIM-174B in size—much larger than the AIM-120.
The concept for the AIM-424 may have been in development for over a decade. In 2017, a senior defense official revealed the Long Range Engagement Weapon (LREW) concept during a defense industry conference. A presentation slide revealed a concept for a two-stage air-to-air missile launched from the internal weapons bay of a stealth aircraft.
"Budget documents in the fiscal 2017 spending request said that the LREW concept had completed a successful, two-year demonstration, and the technology was being transitioned to the services.
The Navy is under pressure to increase the reach of its striking power from the aircraft carrier. China has fielded air-launched anti-ship ballistic missiles and cruise missiles with ranges over 1,000 nm, which requires the Navy to respond with a weapon that can put the missile-carrying aircraft at risk.
The development comes as the Navy and the Air Force are preparing to field the new Lockheed Martin-developed AIM-260 Joint Tactical Missile.
