battle tanks and vetronics to SEPv3
BY John Keller
WARREN, Mich. — Armored combat
vehicle experts at General
Dynamics Corp. will upgrade 45
M1 Abrams main battle tanks and
vetronics to the most advanced
M1A2 system enhancement package version 3 (SEPv3) configuration under terms of a $270.2 million contract.
Officials of the U.S.
Command in Warren,
Mich., are asking General
Dynamics Land Systems
in Sterling Heights, Mich.,
to install and integrate
SEPv2 legacy unique
components resulting in
45 M1A2 SEPv3 Abrams
Main Battle tanks.
The M1A2 SEPv3
main battle tank is the
latest version of the
M1 Abrams, and has
increased power generation and distribution, better communications and networking, a new
vehicle health management system
(VHMS), line replaceable modules
(LRMs) for improved maintenance,
and an ammunition datalink (ADL)
to use airburst rounds.
The contract also asks General
Dynamics Land Systems to procure,
stock, and store 60 sets of SEPv2
legacy and SEPv3 unique components, procure integrated product
support requirements, special tooling and test equipment, and the
systems support package.
This latest version of the M1A2
tank also offers an improved
sive device (IED) armor package,
improved forward-looking infra-
red (FLIR) sensor using long- and
mid-wave infrared, a low-pro-
file Common Remotely Operated
Weapon Station (CROWS), and an
auxiliary power unit (APU) under
armor to run electronics without
the engine running.
Prototypes of the M1A2 SEPv3
tank began testing in 2015, and
should enter service this year.
Improvements to the SEPv3 version focus on increasing the electrical power; improving survivability;
integrating the new Army network;
electronic component improvements; new auxiliary power unit;
and an ammunition data link.
The M1A2 SEPv3 is the next-gen-
eration M1 tank version from the
SEPv2, which focused on improved
survivability, automotive power
pack, computer systems, and
night-vision capabilities. The SEPv2
also offered improvements in
the CROWS and ballistic solution
upgrades for the M829A3 kinetic
and the M1028 canister rounds.
The M1A2 SEPv2 has improved
microprocessors, color flat-panel
displays, improved memory capac-
ity, better soldier-machine interface,
and a new open operating sys-
tem designed to run the Common
Operating Environment software.
The tank gunner’s
primary sight and
mal viewer include
of the new Block
I 2nd generation
intend the M1A2
SEPv3 to defeat
reconnaissance vehicles, infantry
fighting vehicles, armored person-
nel carriers, anti-tank guns, guided
missile launchers, bunkers, infan-
try, and helicopters.
On this contract, General
Dynamics will do the work in Lima,
Ohio; Scranton, Pa.; Anniston, Ala.;
and Tallahassee, Fla., and should be
finished by August 2019. Í
