Evaluation of Future Unmanned Underwater Vehicle
Capabilities in an Automated Computer-Aided Wargame
Using a model-based systems engineering (MBSE) approach in a computer-aided wargame to explore
the effects of advanced UUV capabilities as both an asset in the future U.S. naval fleet and as an
alternative to the dwindling submarine force.
Naval Postgraduate School, Monterey, California

n fiscal year 2016, the Senate Armed
Services Committee ordered the Navy
to increase its fleet to 355 ships. However,
the lack of construction facilities
impedes this endeavor. Rear Admiral
Brian Luther, deputy assistant secretary
of the Navy for budgets, estimated that
the objective of 355 ships will not come
to fruition until the 2050s. As a result,
the U.S. Navy is exploring potential fleet
restructuring options.
There is very high interest in supplementing
traditionally manned naval
assets with unmanned systems. One
such system is the unmanned underwater
vehicle (UUV). With top-level interest
in both fleet and unmanned systems,
the Office of Naval Research (N9)
requested a method and process to test
future capabilities of UUVs and an
experimentation environment or tool
to conduct such investigations. Moreover,
UUVs have traditionally operated
to support mine warfare and minor surveillance
missions, so their impact in
other roles is not understood.
The aim of this research was to use a
model-based systems engineering
(MBSE) approach in a computer-aided
wargame, specifically the Joint Theater
Level Simulation-Global Operations
(JTLS-GO), to explore the effects of
advanced UUV capabilities as an asset in
the future U.S. naval fleet and as an alternative
to the dwindling submarine force.
The MBSE approach is a multi-step process
that explores the whole project from
beginning to end. This approach led to
the development of an advanced UUV
concept and vignette, or concept of operations
(CONOP), from Cobra Gold 2018
(CG18), a six-nation (PACOM sponsored)
command post exercise (CPX). Creation
of the vignette permitted the iterative
examination of CG18 to identify capability
shortfalls that the UUVs could address.
In this case, the vignette focused on
interactions between an enemy
