The Tank is Dead! Long Live the Tank!

(Editor’s note: Amid increasing tensions over the situation in Ukraine, the Russian state media announced it would debut anew main battle tank and infantry fighting vehicle (IFV) during the Victory Day Parade May 9,

2015. These vehicles, the first types in anew family of Russian armored fighting vehicles (AFVs) known collectively as Armata, are intended to replace most of the Russian armored fleet by

2030. The following article describes one possible American response to this development and the generally increasing lethality of today’s modern battlefield. For more information, see http://nationalinterest.org/feature/ the-russian-armys-secret-weapon-enter-the-armata-program-11711. This story links to original Russian announcements.) Predicting the demise of the tank as a principal weapon of land warfare is one of the longest-running pastimes in the study of military history and defense affairs. Before the guns had gone silent on the fields of Cambria, the site of history’s first major tank offensive, the German army had taken its successful blunting of the British attack to mean that the tank was a battlefield novelty of little importance.1 The combination of high-explosive anti-tank (HEAT) warheads and the compact guidance systems in the anti-tank guided missile (ATGM), first deployed in numbers during the Yom Kippur War of 1973, was also supposed to have spelled the end of the tank.2 With the end of the Cold War and the “end of history,” the demise of the tank was again foretold. This era was supposed to mark the end of conventional conflicts, with the tank increasingly relegated to minor and secondary roles, since airpower and Special Forces were to take the lead in brushfire wars the world over. And yet, in each instance, the tank’s unique combination of mobility, firepower and survivability ensured that the tank not only avoided consignment to the trashbin of history, but remains one of the principle expressions of land combat power in the modern age. The Allied tank offensives of 1918 helped ensure victory against the Central Powers.3 The development of advanced composite armors in response to the ATGM threat by British and American engineers under codenames such as “Chobham” and “Burlington” would make tanks like Abrams and Challenger some of the brightest stars of Operation Desert Storm.4 Even in today’s conflicts against non-state actors and state proxies, tanks have repeatedly proven their worth by providing a high degree of tactical overmatch to the armies that employ them.5 Looking forward, the Soldier of tomorrow is likely to face an increasingly complex and lethal environment. Advanced weapons that were once the exclusive reserve of the world’s leading militaries are now finding their way into the hands of second- and third-rate militaries, as well as non-state paramilitary organizations. Recent Israeli operations in the Palestinian territories, such as Pillar of Fire and Protective Edge, have demonstrated that highly sophisticated ATGMs and other precision-guided munitions (PGMs) are becoming increasingly common and are presenting issues once primarily dealt with by the foes of Western militaries.6 In light of this, the author believes that the demand for survivable firepower like that found in tanks will be increasing rather than decreasing in demand. Furthermore, to provide that survivable firepower, the Army should pursue more aggressive modernization of the Abrams than is currently planned, as well as beginning development of anew vehicle that leverages mature as well as developing technologies and design concepts. Only in this way will the Armor Corps remain at the forefront of tank design because, as this article will show, the most exciting developments in AFV technology are often foreign. Assessing past development To remain relevant and capable of contributing to the Army and the joint team’s combat effectiveness, America’s tank fleet must adapt to the changing threat environment. While the M1A2 System Enhancement Program is a world-class tank, the underlying vehicle was commissioned during the Nixon administration and the Abrams is quite nearly at the limits of its growth potential.7 This situation is remarkably similar to the one faced by the Armor Corps in the mid-1970s. The U. S. Army then sought to leap ahead in tank design to make up for a development holiday during the Vietnam War and the combined threat of anew generation of Soviet tanks and increasingly effective ATGMs. At that time, the Army sought to capitalize on research conducted as part of the failed MBT-70 and XM-803 tank development projects.8 By incorporating mature Figure 1, above. The XM1202 tank from the FCS program. Figure 2, right. The MGV chassis.

technologies from the two cancelled programs into the A3 version of the M-60 and pushing forward with 55 critical technology enhancements in the new M-1, the Armor Corps achieved a quantum leap forward in capability while establishing the technical foundations for the dominance the M1 has thus far enjoyed.9 Now the Army is faced with more than a decade’s worth of ground-vehicle re search represented by the now-de funct Future Combat Systems (FCS) manned ground vehicle (MGV) and ground combat vehicle (GCV) programs with no fielded systems to show for it. Also, ground-vehicle design has contin ued to progress in other countries, leading to fielded vehicles with proven features that could be included in future American projects.10 To deal with this state of affairs, the author proposes that the current Engineering Change Proposal 1B (ECP1B)11 being drafted for the Abrams be expanded to incorporate proven and mature technologies not currently slated for inclusion to increase the ECP1B’s utility while anew-build tank is pursued for deployment in the mid- 2020s. This new tank should represent a modest improvement in combat capabilities over the M1A3 but with particular attention paid to design modu larity, built-in growth potential and the ability to incorporate new technologies as they become available. This dual-track strategy would provide increased performance to the warfighter at the soonest possible date while also posi tioning the Armor Corps to take advan tage of cutting-edge and breakthrough technologies as they become available. While the recent edition of Military Review contains an article by Dr. Alec Wahlman and retired COL Brian M. Drinkwine that deals with some of the possible upgrades to the Abrams, this article looks to handle the finer tech nical details of possible upgrades as well as review foreign developments in tank design. Mobility To keep the discussion of proposed features of the M1A3 and anew vehicle somewhat organized, we will group these topics into the three broad cat egories that define the primary attri butes of a tank: mobility, survivability and lethality. In all these domains, the Abrams remains at or near the top when compared to foreign vehicles. While tanks like the Leopard II or Leclerc may be quicker owing to their lower weights, the Abrams’ 1,500-horsepower (1,118.5 kilowatts) makes it one of the world’s most ma neuverable tanks. The advanced Chob ham composite armor and depleted uranium mesh that comprise the Abrams’ current armor package pro vide a level of survivability rivaled only by the British Challenger II with its own advanced composite armor. With re gard to lethality, the pairing of the M256 120mm smoothbore cannon and the M829 family of Armor-Piercing Fin-Stabilized Discarding Sabot (APFSDS) is Figure 3. The Leopard II A7, displayed at Eurosatory 2010. (Photo from Wikimedia Commons; used per applicable licensing “Attribution 2.0 Generic (CC BY 2.0)”) one of the most effective pairings of gun and ammunition in the history of armored warfare. Despite all this, the fact remains that ground-vehicle tech nology has continued to progress and that the Abrams could stand to gain considerably from leveraging these ad vances. Turning first to the M1A3, significant increases in capability across all three domains are already planned by General Dynamics Land Systems (GDLS) through ECP1B.12 Dealing first with mo bility, GDLS has proposed several improvements. Chief among these is the Abrams dieselization initiative. The MTU-833 CRI diesel engine, similar to the engine found in the Leopard II, will replace the 1,500-horsepower Honey well AGT1500C turbine engine. While providing the same power as the gas turbine, the diesel engine will deliver a 50-percent increase in cruising range through enhanced fuel efficiency and a 37 percent reduction in maintenance costs owing to greater simplicity and higher commonality with commercial diesel engines.13 Another mobility improvement, also courtesy of the Leopard II, is the Dehil 570 P-series track and road wheels, which last 20 percent longer than the current generation of track while also reducing the vehicle’s acoustic signature.14 In-arm pneumatic-suspension units replace the torsion-bar suspen sion and complete the planned mobil ity enhancements.15 Enhancing reliabil ity, the M1A3 will also include suite of on-board diagnostics that increase the speed and accuracy of maintenance.16 When taken together, the mobility en hancements proposed by GDLS repre sent a significant improvement to the status quo. Also, if slightly elevated design risk is deemed acceptable, two technologies researched for the FCS MGV program stand consideration as mobility en hancements as well. The FCS MGVs were to be powered by diesel-electric hybrid engines that provided huge improvements in fuel efficiency as well as improved electric-power-generation potential.17 Segmented band track, a continuous rubber track with metal inserts, is an other technology originally developed for the FCS that would enhance the M1A3’s mobility through a reduced roll resistance, reduced acoustic signature, reduced weight and longer lifespan when compared to conventional metal tracks.18 Survivability Turning to survivability, GDLS is proposing to include unspecified sensors providing 360-degree situational awareness and an active protection system (APS) on the next iteration of the Abrams tank.19 While both of these would represent first-of-their-kind sys tems on American ground vehicles, they have already been fielded and, in some cases, are battle-proven with foreign armies. A case in point would be the Trophy APS developed by Rafael. This system consists of a series of millimeter-wave radar sensors that create a hemispher ical area of coverage around the protected vehicle. After detecting an in coming threat, such as a rocket-pro pelled grenade, the system launches an explosive countermeasure to inter cept the round before it impacts the vehicle. These systems have been com bat-proven with the Israeli army, which took a brigade’s worth of the equipment to Operation Protective Edge to protect the Merkava IV tanks. The sys tem also calculates the point of origin of the incoming round and provides the ability to slew the main gun to that point.20 Another mature technology ready for inclusion in ECP1B is the SSP-1 OBRA-3 Laser Warning System by Polish Defence Holdings. This system detects laser radiation commonly used in range-finding equipment and alerts the crew to the location of the laser range finder. Four sensors mounted on the vehicle provide 360-degree coverage and the same slew-to-cue capability found in the Trophy APS.21 Both sys tems are also capable of autopopulat ing battlefield-management software with the point of origin for each detected incoming threat. By allowing the M1A3 to perceive the threat before it can engage, avoid be ing hit if engaged and shorten the time it takes to acquire the threat, systems like Trophy and SSP-1 provide a signifi cant improvement over the Abrams’ al ready impressive survivability while re quiring little to no more development prior to integration, since these systems are both designed as plug-and-play after-market additions to mature vehicle designs. This is, in fact, a major source of the marketability stressed by the manufacturers and could be lever aged for rapid fielding to the current fleet of Abrams tanks. Lethality Moving to lethality, GDLS is looking to integrate an ammunition datalink that would allow use of the projected advanced multi-purpose (AMP) 120mm round.22 Seeking to improve the Abrams’ target-acquisition capability, ECP1B may also include a third-generation forward-looking infrared (FLIR) sensor suite.23 While replacing four ex isting rounds, the AMP round does not provide an increase in lethality so much as take the guesswork out of Figure 4. The Merkava IVm with Trophy APS.

what round should be battle-carried.24 An increase in lethality could be achieved through integrating technol ogies already found on foreign vehicles. The M256 120mm smoothbore cannon that currently equips all M1 tanks in service is a license-built copy of the Rheinmetall L44 120mm, refer ring to the fact that the length of the gun is 44 times its 120mm bore.25 Leopard IIA6 and all subsequent versions mount the Rheinmetall L55 120mm gun.26 The additional 25 per cent in barrel length imparts a higher muzzle velocity and accuracy to rounds fired from the gun. As demonstrated in the inclusion of the L55 on the Leopard IIA6, the high degree of commonality with the L44 makes integration of the longer gun relatively simple.27 A further increase requiring minimal development would be the certifica tion of Israeli Aerospace Industries’ La hat ATGM for use in the Abrams. The Lahat ATGM can be launched from a variety of platforms, including from the main gun of tanks with 105mm and 120mm guns.28 By extension, the Abrams’ M256 should be compatible with the Lahat ATGM. The round’s range of 4.97 miles (eight kilometers) from ground platforms would significantly enhance the Abrams’ reach, which – even when equipped with an L55 type gun firing conventional munitions – would be about 2.5 miles (four kilometers).29 This increased reach would close the gap that exists be tween the Abrams’ maximum engage ment range and the 3.1 mile (five kilo meters) range of tanks like the T-80 and T-90 when equipped with the AT- 11 Sniper ATGM.30 To maximize the po tential of the standoff range provided by Lahat, ECP1B should also seek to le verage the manned-unmanned team ing capabilities being developed as part of the AH-64E Block III program.31 The ability to manipulate unmanned aerial vehicles would permit the Abrams to use remote systems for tar get designation and use Lahat to achieve a true beyond-line-of-sight en gagement capability. New-build vehicle All the upgrades described previously would significantly enhance the Abrams tank’s performance. The fact remains, though, that the vehicle will be approaching 40 years in service by the time these upgrades could come to fruition. Anew-build vehicle is are quirement. If the need for this vehicle is clear, the features and capabilities are not as concrete. Still, the trends discussed previously should give a good sense of where the new vehicle needs to go in terms of development, what threats it should be able to ad dress and what capabilities it should have. Given a typical developmental time line, requirements drawn up today must seek to discern the environment in which a given system will operate years in the future. While doing this with any accuracy is difficult, the trends of the present hold alight to the way of the future. As discussed earlier, recent and ongoing conflicts in the Middle East demonstrate that even future conflicts with non-state actors will bring our Soldiers and armored ve hicles into contact with advanced ATGMs, other PGMs and the sensors that go with these weapon systems. The diffusion of weapons and technol ogies once exclusively held by Western militaries will define the battlefields of tomorrow. To counter this, a future tank must seek to exploit the asym metrical technological advantages of American and allied militaries: advanced lethality solutions, sensors and sensor fusion, and network solutions. As the pace of both technological change and the evolution of the threat environment increase, the ability of a platform to adapt over time must be a conscious design attribute. Modularity and excess space, weight and power must be built into the design. Turning first to mobility, anew-build vehicle should take full advantage of the research in hybrid drive trains con ducted for the FCS and GCV programs. A vehicle equipped with such an engine, and the band track discussed ear lier, would benefit from much improved fuel efficiency and accelera tion, as well as from generating plenty of excess electrical power. Also, when running on electric power, the new tank would be able to virtually eliminate its acoustic signature and thereby open up new maneuver possibilities and increase its own survivability. Reducing signature Moving to survivability, a future American tank must embrace a concept of layered defense because the enemy cannot engage what it does not see, cannot damage what it cannot hit and cannot kill what it cannot penetrate. To ensure the enemy cannot see the tank of the future, signatures of all types must be reduced when compared to the current generation of vehicles. The current state-of-the-art in cross-spectrum signature reduction for ground vehicles is the Polish PL-01 concept tank. The vehicle’s visual signature is diminished by reducing the standard four-man crew to three by re placing the loader with a mechanical autoloader and moving all crew members into the hull. The resulting un manned turret has a very low profile and the reduced space required by the crew limits the vehicle’s protected volume, reducing its weight and size over all.32 The PL-01’s radar signature is reduced by applying radar-absorbent material to the vehicle’s skin and shaping its surfaces to minimize the probability of a surface being perpendicular to a ra dar receiver.33 The infrared (IR) signature reduction is perhaps the most intriguing part of the whole vehicle. A matrix of hexagonal plates on the ve hicle’s skin can change its temperature to match that of the environment on the vehicle’s opposite side, giving it the ability to disappear from view in an IR sensor.34 The vehicle may even call for ward a false IR signature from an onboard library, allowing the 35-ton tank to take on the appearance of a passen ger car or anything else it might choose to imitate.35 More IR signature reductions are achieved by active cooling of the PL-01’s exhaust.36 The hybrid diesel engine and band track discussed earlier would serve to reduce a future American tank’s acous tic signature. Having made the new-build vehicle harder to see, the work of making it harder to hit will also rely on across-spectrum approach. Laser warning systems would warn the new tank that a threat has begun an en gagement sequence. Millimeter-wave radars installed on the vehicle as part of an active defense system would alert the vehicle to the presence of an incoming round. If the vehicle was un able to evade the detected threat, the APS would engage the incoming round and prevent the vehicle from being hit. If all these countermeasures were de feated, it would fall to the new tank’s passive armor to defeat the incoming rounds. Modular armor A modular-armor concept built around the idea of tailorable levels of protection should be the basis for the future tank’s passive protection. Modular ar mor is widely applied to European ar mored vehicles. The PL-01 makes ex tensive use of modular-armor mod ules, as does the Leopard II. The modular-armor design provides a number of important benefits:

• First, the level of protection the ve hicle carries is no longer fixed, as is the case with the Abrams. The Abrams tank must carry the incred ibly heavy armor that shields it from APFSDS and HEAT rounds even on patrols where the most serious threat it will face are small arms. Modular armor allows the vehicle crew to tailor the level of protection to the threat level, carrying the appropriate level of protection and not more.

• Second, modular armor allows for rapid replacement of damaged modules.

• Finally, modular armor allows ave hicle’s armor to upgrade as mate rial technology advances without a major redesign of the vehicle or costly retrofits. Cannon Third, and perhaps most importantly, we turn to the lethality of the pro posed new-build vehicle. While the Abrams has been equipped with the M256 120mm smooth-bore cannon since the 1980s, the survivability of its targets has increased greatly. The T-90, the most advanced tank fielded by Russia and other states, combines com posite armors and Kontakt-5 explosive reactive armor to achieve a protective power equivalent to 4.4 feet (1.34 me ters) of solid steel.37 When the effects of APSs are factored in, the current weapon systems suite in the Abrams seems barely adequate. A future tank will likely be fielded initially with a ver sion of the M256, but a potential for a more lethal weapon must be built into the turret of the new vehicle. Shortly before the end of the Cold War, American and West German tank de signers projected that future Soviet tanks would be immune to the 120mm and began design work on 140mm cannons.38 The 140mm cannons were intended to provide muzzle energies of roughly 18MJ, or twice that of the 120mm cannons deployed on Abrams and Leopard II.39 A gun of this size will make an autoloader a near necessity and will require a larger breach block and larger recoil space, all of which will impact turret design before a 140mm gun is even ready for fielding. Another option for increasing the hit ting power of main-gun projectiles is the pursuit of electro thermal-chemical propellant ignition. These guns achieve higher muzzle energies by ig niting propellant through a plasma cartridge that is catalyzed by electrical impulses.40 This method of ignition great ly increases the consistency and effec tiveness of the propellant ignition and delivers huge improvements in perfor mance.41 A U. S. Army study conducted in the late 1990s with a prototype 120mm electro thermal-chemical gun designated the XM-291 achieved muz zle energies of 17MJ, or just below those achieved with the larger 140mm prototypes.42 A future tank capable of fielding a gun with such energy would be assured of defeating the protective systems of all fielded armored vehicles and any projected vehicles the author is familiar with. Sensors As always, though, the key to maximiz ing the potential of these weapons lies in the ability to perceive a threat. Third-generation FLIR is being consid ered for inclusion in Abrams’ ECP1B, a development that will ensure the full use of advanced munitions currently being researched. Millimeter-wave ra dars in APSs as well as laser-warning systems (LWSs) provide a level of 360-degree awareness to select foreign ground vehicles today and could be incorporated into M1A3, as dis cussed earlier. To enhance this level of 360-degree situational awareness for the new-build vehicle, the future tank should include systems similar to the AN/AAQ-37 Distributed Aperture System (DAS) fielded on the F-35 Joint Strike Fighter (JSF). This system – six sensors embedded in the skin of the aircraft – provides the JSF 360-degree IR search and track as well as missile-launch detection. This information is fused into a single picture and is super imposed onto a helmet-mounted Figure 5. The Polish PL-01.

display that permits the pilot to see through the skin of the aircraft as if it were glass.43 While the ground environment the fu ture tank will inhabit is more cluttered than the one inhabited by the JSF, sen sors like the DAS, combined with sen sor fusion, would permit the tank to shed its traditional lack of situational awareness imposed by its armored skin. Sensor fusion would permit the seamless integration of information from IR, daytime television, LWS, mil limeter-wave radar and other sensors into a single picture of the operating environment. Leveraging the network in conjunction with these sensors would permit the future tank to achieve a level of situational aware ness and, therefore, lethality that Abrams crews can only imagine. While some people might consider all this su perfluous and unneeded, consider that American tank crews who witnessed the transition from M1A1 to M1A2 have already witnessed the potential of sensors to increase their lethality. The Commander’s Independent Thermal Viewer (CITV), mounted on the M1A2’s turret, permits the command er to search for targets while his gunner executes an engagement cycle. The Force XXI Battle Command Brigade and Below allows the commander to in stantly share information from his CITV with other networked vehicles. A fu ture tank that is enabled by a suite of sensors providing 360-degree stare across the electromagnetic spectrum will only accelerate the increase in le thality realized by previous Abrams up grades. Tank is dead This article has covered a lot of ground in discussing the future of armored firepower for the U. S. Army. The vari ous topics from the changing threat environment to advances in ground vehicle protective systems, to historical parallels in defense acquisitions, could each justify books in their own right. And of course, this author would be re miss if he did not acknowledge the of ten-decisive role of tank-crew training and its ability to magnify or overcome materiel superiority. For the sake of looking at the future’s broad outlines and what capabilities a future American tank must encompass, some devel opments such as directed-energy weapons were not mentioned. Some cutting-edge vehicles, like the South Korean K2 or Japanese Type 10, were also passed over. This is not to say that these ideas and vehicles do not represent important advances in the state of the art or that some of their features should not be included in a future American tank. The existence of so many vehicles with whole sets of capabilities currently ab sent on American ground vehicles con firms two things. First, the tank as we know it is dead. Second, the tank as a means of delivering survivable fire power to the decisive point on an increasingly complex and lethal battle field has a bright future enabled by ideas and technologies unimaginable a few short years ago.
