It depends on what kind target it is. If it is a hardened bunker, then a circular error of 3 meters may as well be 30 meters away.some clarification in trishul blog
'"LGB missing" - it did not miss! All LGBs have a circular error probable, ranging from 10-30 m for non GPS assisted ones, within which if the bomb falls, the primary target is destroyed once the explosives do their job. In this test, clearly, the Sudarshan was launched without any HE and still came well within 10 m of the target, which in real life would devastate the target with its HE warhead!"
