U.S. Army 'Moving Rapidly' To Add V-Hull to Strykers - Defense News: "In January, Stryker manufacturer General Dynamics presented the Army a plan to accelerate the introduction of a double V-shaped hull to the flat-bottomed Stryker, increasing the vehicle's protection against improvised explosive devices.
One source said the Army currently plans to reduce monthly Stryker production from 35 to 20 by January, which could delay the improvements. The source said that if the vehicle's production rate is held steady, the company could deliver 130 vehicles in the infantry carrier configuration in time for the next Stryker brigade's deployment to Afghanistan in July 2011."
