|
# This file contains definitions for the 'mover', guidance computer, fuse and
|
|
# lethality and a base platform type. It should be considered a rudimentary
|
|
# beginning point for further refinement. The user is then responsible for:
|
|
#
|
|
# A) Creating a 'platform_type' that derives from BLUE_SR_A2A_IR_MISSILE_BASE which defines
|
|
# the seeker and any other subsystems that may be required.
|
|
#
|
|
# B) Creating a 'platform_type' that represents the launcher.
|
|
#
|
|
# The last part of the file is commented out and demonstrates the above steps.
|
|
#
|
|
# All information below is representative only, and is estimated or obtained
|
|
