AFAIK P3I was a proposal based on the results of US testing in 1995, not the missile as evaluated by the US
In January 1995 British Aerospace Dynamics, Stevenage, Hertfordshire, England, was awarded a letter contract with a ceiling amount of $10,933,154 for foreign comparative testing [FCT] of the ASRAAM Missile. The purpose of the testing is to gather data to determine if the missile meets AIM-9X operational requirements. Work was performed in Stevenage, Hertfordshire, England (50%), Eglin Air Force Base, Florida (25%), and China Lake, California (25%), and was completed by June 1996. The tests focused on the risk areas of the ASRAAM: focal plane array effectiveness, seeker signal processing, warhead effectiveness, rocket motor testing, and kinematic/guidance ability to support the lethality requirements of the AIM-9X. After several modifications to the scope of the FCT, the program assessed four ground-to-air sorties, 19 air-to-air captive carry sorties, four programmed missile launches, eight static warhead tests, and four rocket motor case tests. The resulting assessment was that the ASRAAM (as is) could not meet the AIM-9X operational requirements in high off-boresight angle performance, infrared counter-countermeasures robustness, lethality, and interoperability. Subsequently, Hughes and BAe proposed an improved “P3I ASRAAM” using thrust-vectoring to provide increased agility and to carry a heavier warhead.
In aerodynamics, to calculate the resulting aerodynamic force you use a reference surface which depend on aerodynamic body.
Resulting aerodynamic force
For lifting bodies (ie aircraft) you take wing platform area
Wing platform area
For slender body (missile, rocket, ammunition) you take the body cross section
Body cross section
For bluff bodies (car/ train) you take the frontal area.
Frontal area
Since the formula of the resulting aerodynamic force is:
Force= 1/2* air pressure around the object * (speed around the object)^2 (=speed of the object)* Reference surface * Aerodynamic shape efficiency (depend of the Mach number, the Reynold number, the shape of the object and the angle of attack).
Anyways the having a lifing body mean that it uses it’s body as a reference surface which GREATLY increase it’s lift which mean it can achieve greater range.
The pre-war 500lb bombs with the explosive load of the American 250lb bombs. They just gave the 500lb M.C bombs to the Beau’s but not anything else.
After further research it seems that the Wyvern also got the M.C bombs.
The Shackleton has the 500lb Mk.II bombs so I don’t see why the Sea Hawk shouldn’t.
