MMT software has shown potential for
surface-launched applications (e.g., sur-
face-to-surface and surface-to-air). e
demonstration phase of MMT includes a
series of surface launches as part of the
crawl-walk-run ight test plan.
e combination of MMT's open sys-
tems architecture algorithms and the
simulation environment has resulted in
other development time savings. MMT
develops its algorithms in a six-degrees-
of-freedom (6DOF) simulation that
models the missile's ight trajectory.
e 6DOF simulation is coded in an
object oriented programming language
(C++) in a manner intended to be directly
compatible with real-time processing.
us the relevant guidance and control
code from the MMT 6DOF simulation
can be copied directly into the C++ com-
piler for the missile's real-time ight
processor in one step. Normally the tran-
sition from the simulation environment
to the ight hardware is a months-long,
labor-intensive process with multiple
steps. With its one-step process, MMT
has reduced the simulation-to-real-time
processor transition from months to days,
saving development money as well as time.
e MMT 6DOF simulation is just as
modular as the MMT hardware. e sim-
ulation has been built to permit di erent
subsystem models to be swapped in and
out at will, and to do so in a closed-loop
environment, modeling the behavior of
the system, that allows rapid performance
evaluation of the resulting all-up round.

For instance, a small business with a
new seeker idea, such as a component or
data-processing method, could receive

tiple vendors simultaneously, enabling a
very competitive prototyping acquisition
strategy. is capability was successfully
beta-tested in July 2014 in a collabora-
tive e ort between MMT and another
AMRDEC seeker S&T program.
e combination of the MMT modular
open systems architecture and the sup-
porting simulation tools that have sprung
from it combine into a powerful and
innovative acquisition tool, permitting a
project o ce to act as a lead systems inte-
grator for a guided missile system.
As such, the government would be able
to rapidly develop multiple prototypes
before deciding on one (or more) for an
initial capability. From there, the govern-
ment would be able to experiment with
new subsystem prototypes to reduce the
cost, improve the existing capability
or develop a new capability. e result-
ing system would be the best solution
that the entire missile industrial base
could produce, rather than just the best
(proprietary) system that a single prime
contractor team could produce.
e ability to compete individual sub-
systems also expands the competitive
environment by creating openings for
small businesses and other companies
that have not traditionally participated
in the development of a guided missile.
MMT's modular open systems archi-
tecture provides another avenue for the
Army and DOD to innovate more rap-
idly and at lower cost.
