Executive Summary, This report provides my operational assessment of the Handheld Manpack Small Form. Fit HMS AN PRC 155 Manpack radio and Joint Enterprise Network Manager JENM It is. based on the results of the Manpack radio Follow on Operational Test and Evaluation FOT E. the Army Test and Evaluation Command ATEC conducted at White Sands Missile Range. New Mexico and Fort Bliss Texas in May 2014 This assessment is augmented by the results. of Government Developmental Test GDT 4 conducted from January through February 2014 at. Fort Huachuca Arizona,Operational Effectiveness, The Manpack radio was not operationally effective when employed in dismounted. operations during the FOT E This assessment is the result of the Soldier Radio Waveform. SRW not providing sufficient range to support dismounted company and platoon level. operations The use of SRW on the Manpack radio for voice communications degrades a unit s. capability to exercise command and control in comparison to currently fielded radios operating. with the Single Channel Ground and Airborne Radio System SINCGARS waveform The. Manpack radio was operationally effective for mounted operations Vehicular mounted. Manpack radios mitigated SRW range limitations due to higher vehicle mounted antennas. Additionally the mounted test unit had a higher density of Manpack radios and hence a denser. network aiding communications in comparison to the dismounted test unit. Dismounted Operations, At company and platoon level voice communications are the primary and most critical.
means for tactical leaders to exercise mission command Impaired voice communications. adversely affect the ability of a platoon or company to successfully execute its tactical mission. During the FOT E units operating dismounted radios were not able to maintain reliable. voice communications using SRW due to the waveform s inherent range limitations Units. employing SRW voice communications will have a reduced point to point range in comparison. to the legacy SINCGARS Advanced System Improvement Program ASIP radios This. outcome is directly explainable by the physics of waveforms Higher frequency waveforms have. a shorter range than lower frequency waveforms and are more affected by terrain obstructions. During the FOT E the company network operated on the Ultra High Frequency UHF band. and the platoon networks on L band Both of these bands are higher frequency than. SINCGARS which operates in the Very High Frequency VHF band. During the final FOT E focus group discussion all three infantry rifle company. commanders along with all eight unit radio operators present stated they would not want to take. the Manpack radio to combat The main reason the commanders gave was the inability to. communicate by voice with subordinate units The cavalry troop commander stated in his focus. group It is harder to communicate in this unit in comparison to his unit in Afghanistan and I. Mounted Operations, During the FOT E the Manpack radio was operationally effective for mounted. operations The cavalry troop predominately operated the mounted radios and the SRW network. performed satisfactorily in their vehicles This was the result of three principal factors First. vehicular mounted Manpack radios mitigated SRW range limitations due to higher vehicle. mounted antennas Having a taller antenna enabled the radio transmissions to more easily. overcome the micro terrain that hampered the dismounted Manpack radio operators Second the. mounted test unit had a higher density of Manpack radios and hence a denser network aiding. communications in comparison to the dismounted test unit Third the cavalry troop operated in. less restricted terrain than did the three infantry companies Nevertheless physics still dictates. that SRW will have a shorter range and be more sensitive to terrain obstructions than the. SINCGARS waveform, Single Channel Ground and Airborne Radio System SINCGARS Waveform. During the FOT E SINCGARS waveform performance on the Manpack radio improved. from that demonstrated in the Manpack radio Multi Service Operational Test and Evaluation. MOT E in 2012 where DOT E evaluated it as not operationally effective During the. FOT E there were no observed issues with the Manpack radio s SINCGARS range or. connectivity,Satellite Communications SATCOM Waveforms. The FOT E was not adequate to evaluate the effectiveness of the three satellite. communications SATCOM waveforms operating on the Manpack radio Due to satellite. availability each of the SATCOM waveforms 181B 182A and 183A was available for only. one 72 hour window As a result there were insufficient SATCOM operating hours for an. adequate evaluation Additionally the unit had difficulty connecting to the satellite with all three. SATCOM waveforms The source of this connectivity problem is not known the numerous. failures to connect to the satellite may have been due to the unit being assigned a lower priority. than other users of the same satellite A lower priority would deny the Manpack radio operator. access to the satellite if higher priority users were using the SATCOM channel. Two Channel Operations, The ability of the Manpack radio to simultaneously operate on two channels worked well. and was noted as positive by the Soldiers in the FOT E In normal operations a Manpack radio. operator could have one channel on his unit network and the other channel on an alternate. network to obtain a simultaneous connection This ability to have two channels in one radio is. valuable to leaders and operators who may need to operate on two different networks. Multiple Waveforms, The Manpack radio is a software defined radio that can operate five different waveforms.
Having multiple waveforms available on a single radio enhances a unit s flexibility During the. FOT E the capability to switch between different waveforms enhanced unit operations. Joint Enterprise Network Manager JENM, The JENM was able to plan configure and load all necessary configuration files into the. Manpack radios used in the FOT E The JENM operated as intended and had the necessary. capability to perform these functions However the process for planning a network is. cumbersome and the time to load all of the Manpack and Rifleman Radios in a unit is excessive. taking as long as 24 hours for a single company,Operational Suitability. The Manpack radio is not operationally suitable The weight of the radio with a 24 hour. load of batteries is three times the legacy ASIP radio This increase is not acceptable for. dismounted operations and is a burden to the Soldiers carrying the radio The reliability of the. Manpack radio has improved from what was measured in the MOT E and is assessed as reliable. for the Soldier Radio Waveform SRW Although the SINCGARS waveform did not meet its. reliability requirement its reliability did not adversely affect the test unit s ability to execute the. mission The SATCOM waveform 183A did not meet its reliability requirement The reliability. of the satellite SATCOM waveforms 181B and 182A cannot be determined due to insufficient. operating hours, The heat given off by the Manpack radio is within the Military Standard for safe. operations but made several of the operators uncomfortable The training was good for most. operators but leaders needed more instruction on how to employ an SRW network in their unit s. concept of operations, The JENM training was satisfactory It included classroom time and a practical exercise. where new users planned and loaded the configuration files for each type of radio supplied to. their respective units,Survivability, The Manpack radio is not survivable in its current configuration The Army Research.
Laboratory Survivability Lethality Analysis Directorate ARL SLAD conducted a Step 4. cooperative analysis of the Manpack radio and SRW network The Army s Threat Systems. Management Office with assistance from ARL SLAD led a Step 5 adversarial assessment The. Threat Systems Management Office conducted electronic warfare via communications jamming. of the SRW radios and unreliability jamming The complete survivability evaluation is. contained in the classified annex,J Michael Gilmore.
