3.FIRE CONTROL
M777A1
Fire Control
In the dead of night or the thick of a storm, the M777 can fire its
massive artillery with accurate precision - directly or indirectly
- thanks to its optical fire control system, which is digitally
compatible. A killer feature is its compatibility with the new
Raytheon XM982 Excalibur GPS/Inertial Navigation-guided extended
range 155mm projectiles. These babies have a maximum range of 40km
and a circular error probability (CEP) of 10m. Now that's
precision. Initial testing of the Excalibur was in August of 2003,
and initial fielding is expected for 2006.
How about Spore's?Do we have guided ammo?Authorised info

PICATINNY, N.J. -- April. 06, 2005 -- A joint-service program
office here at Picatinny has completed development and is managing
the purchase of 495 new lightweight 155mm howitzers for the Marine
Corps and the Army, a spokesperson for both services has
announced.
An $843 million four-year contract has been awarded to BAE Systems,
Barrow-in-Furness, UK, to manufacture the weapons and 94 digital
fire control retrofit kits, according to Jim Shields, deputy
program manager for the lightweight 155mm howitzer program.
Shields said that the howitzer, known as the M777A1, howitzer in
the services inventories.
The M777A1 will replace all of the Corps current M198 towed
howitzers, he said, and will be the artillery system for the
Armys Stryker Brigade Combat Teams. .......
All 495 full-production units will be manufactured with digital
fire control systems also known as towed artillery digitization or
TAD.
The M777A1 will be capable of firing the Armys Excalibur
precision-guided projectile that is also under development here at
Picatinny. Excalibur will be fired out to a range of 40 kilometers
from the M777E1 and because of its GPS and inertial navigation
guidance, will deliver precision strike capability (
two can fit on the C-130.....
Excalibur is scheduled to be fielded in late 2006 when the Army
starts taking delivery of their first M777A1s.

[quote]In November 2002, Land Systems was awarded a $135 million
contract by the US Department of Defense (DOD) for the low rate
initial production of the M777 155mm lightweight towed
howitzer.
Under the initial phase of the contract, Land Systems will
manufacture 94 M777s for the US Marine Corps (USMC) with the first
weapons delivered in February 2004 from the company's facility in
Hattiesburg, Mississippi.
It is expected that the USMC will take delivery of 377 systems to
replace the heavier M198 155mm towed howitzer with the US Army also
acquiring 273. Full production is due in January 2005 when 20
systems will be produced each month.[quote]
