Railgun EMRG: a new stage of testing and a great future
Latest events
The Naval Research Administration of the United States Navy and a number of related enterprises spent the first months of this year preparing for the next test of advanced weapons. At one of the sites of the Naval Surface Warfare Center (NSWC), an EMRG prototype was deployed.
The product was transported from another landfill, where its design was previously tested. "Relocation" was associated with the need for a new phase of testing. In the near future it is planned to check the characteristics of the firing range. Due to the large estimated firing range, the prototype EMRG rail gun needs a range of appropriate sizes. As representatives of the Navy recently clarified, installing the unit with a gun on a new site was not an easy task and required considerable effort.
The trials started on May 15. The purpose of the first firing was to check the performance of the newly assembled unit. It was necessary to check its strength, to test the energy systems and the instrument itself. According to the original plans, four-shot trials should take three days. However, the absence of breakdowns and significant difficulties allowed to cope for two.
The EMRG cannon executed four shots. The installation generally performed well. Any corrections or improvements on the results of the test are not needed. Due to this, the prospective sample can continue testing according to the approved program. In the near future, he will have to confirm the calculated characteristics of range and accuracy - for which he was transferred to the current site.
Expected future
The EMRG rail cannon project is being developed in the interests of the US Navy and with an eye to the distant future. Based on this product or using the technologies used, it is planned to create a promising artillery system for surface combat ships.
However, the Navy does not yet specify when the rail cannon will be transferred from the ground stand to the trial vessel. The existence of such plans has been mentioned for the past few years, but they have not yet been implemented. Moreover, the fleet is in no hurry to even name the approximate dates for such work. For the time being we can only assume that carrying out the current tests for range and accuracy will in the future allow us to proceed to the next stages of the program.
Also, the question of the future carrier of EMRG remains open. Rail gun makes special demands on the power systems of the ship, which limits the range of their carriers. For some time it was mentioned that the rail gun for the US Navy will be mounted on destroyers of the type Zumwalt. These ships were originally designed taking into account the use of systems and weapons with special requirements for energy. The first carrier of EMRG could be the ship USS Lyndon B. Johnson (DDG-1002). However, the further construction of such destroyers is not planned, which raises some questions.
Involving ships or vessels of other types to be tested presents a known difficulty. Before mounting a rail gun, they may need to seriously modernize the design, as well as rebuild the power systems. Such works will noticeably affect both the duration of the program and its cost.
Desired benefits
The development of the EMRG tool is carried out with the aim of further development naval weapons and replacement of existing artillery systems. 155 mm naval guns are capable of attacking targets at ranges of tens of kilometers; rockets work at great distances. Promising rail cannons are seen as capable of firing farther than traditional weapons and cheaper to operate than missiles. However, to achieve these benefits, it still requires completion of a massive development and testing program.
According to current plans, in the distant future, some US Navy ships will have rail guns with ammunition from modern shells. A promising HVP (Hyper Velocity Projectile) ammunition is currently under development. When launched from an EMRG or similar instrument, it will be able to develop hypersonic speed, which ensures firing at a range of 100 miles. Modern guns of the traditional design have already been able to send HVP to 45-50 miles.
The EMRG cannon and the HVP projectile have already been tested together and confirmed the fundamental possibility of obtaining the desired characteristics. However, the further development of such a complex and its prospects in the context of the rearmament of the Navy are directly dependent on the ongoing work at the NSWC test site.
It is expected that after the completion of current programs, surface ships of compatible types will be able to get modern and highly efficient artillery armament based on new principles. With the help of conventional and hypersonic projectiles rail guns will be able to attack targets at distances of hundreds of kilometers and accurately hit them. Destruction will be provided by both the warhead of the projectile and its kinetic energy. In some cases, the ships will be able, as before, to use powder artillery or missiles.
Unsolved problems
The plans of the US Navy in relation to rail guns look very bold and may disturb the likely enemy. However, as long as they are far from complete implementation. The fleet project EMRG, despite recent successes, is still not ready to provide re-equipment of surface ships. In addition, there are difficulties of a different kind.
First of all, rearmament remains a matter of the future because of the need to continue work on the rail gun itself. Just a few weeks ago, it was deployed on a new site, which allows for tests with shooting to the maximum distance. In this case, information on the conduct of such shooting has not yet been received. At the moment, it is impossible to say with certainty how long they will last and how they will end.
The US Navy does not have to solve the simplest question of an experimental vessel to test EMRG at sea. Further similar problems will appear, but on a different scale. Mass introduction of rail guns is impossible without appropriate carriers. To do this, it will be necessary to carry out a rather complicated modernization of cash ships or to develop completely new projects, initially taking into account the special requirements for energy.
Finally, the EMRG project may become a victim of politicians. Programs for the creation of rail guns have been going on for many years, but no such sample has yet been brought to military service. Dear and long-term work without a visible practical result naturally becomes a reason for criticism. It is quite possible that in the near future calls for the abandonment of the EMRG program will re-sound due to its high cost and inefficiency.
Enviable optimism
Nevertheless, the project developers and associated structures of the US Navy remain optimistic and continue to work. Recently, they began a new phase of the program, the implementation of which will bring closer the moment of creating a full-fledged combat system for ships.
At this stage, the developers of the EMRG cannon can only boast of successful execution of firing to confirm the efficiency of the newly mounted installation. However, in the near future a new stage of test firing is expected, during which it is planned to reach the maximum performance. The US Navy looks to the future with optimism, although they understand the complexity of the upcoming work.
