The weapons we have now were build when we could hit within 500 feet of the target,
now we can hit within 5 feet with GPS guidance systems
With a bomb that hits within 5 feet you do not need a yield of 50 to 100 KT
that was great for the bombs that could hit within 500 feet.
20 years ago to take out a C3 bunker you needed to hit it with a 100KT weapon.
Now you use a 5KT GPS guided nuclear deep penetrating bunker buster.
Yes we need to up grade our nukes to reduce there yield and improve the guidance systems to be able to take out there target without a excess of collateral damage.
The weapon demonstrated its range in May with an 88 km flight from an altitude of 30,000 feet, hitting within 85 cm of its target.
Boeing completed SDB development testing in September 2005. In development testing, 37 SDBs were released against fixed targets. Thirty-five weapons were successful, each hitting within an average of 1.1 m from its surveyed target aim-point. Key tests included the single-pass release of four bombs against four separate targets, at a range of 37 km. The weapon demonstrated its range in May with an 88 km flight from an altitude of 30,000 feet, hitting within 85 cm of its target. In a test with effective GPS jamming in May, a bomb flew 56 km and landed within 2 m of its designated impact point, using its inertial measurement unit and onboard logic to overcome jamming.
The secret to the SDB's precision is the Accuracy Support Infrastructure (ASI), developed and supported by SRI International. Based on USAF technology programmes from the 1990s, this comprises ground stations that detect errors in GPS and transmit correction signals. ASI stations can be located up to 2,400 km apart, making it possible to cover an entire theatre from neutral or friendly territory. This improvement in accuracy is applicable to any GPS weapon with the correct receiver.
the best a penetrator can `dig` into rock is around50 meters , using a secant ogive shape with rocket assistance.
