Missile flight testing scheduled for 2025 has been pushed back to 2027. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cDespite recent successes testing the CPS missile, the Navy faces several programmatic challenges associated with developing, delivering, and deploying the CPS missile on the DDG-1000,\u201d warned the Government Accountability Office <a href=\"https:\/\/www.gao.gov\/products\/gao-26-107974\" target=\"_blank\" rel=\"\"><u>report<\/u><\/a>. \u201cThese challenges include rising costs, schedule delays, reliability issues with DDG-1000 class destroyers, and CPS production challenges, among other things.\u201d <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In search of a mission for the DDG-1000 after escalating costs and capability concerns resulted in the program being cut from 32 ships to just three, the Navy decided in 2022 to arm the Zumwalts with CPS <a href=\"https:\/\/www.dote.osd.mil\/Portals\/97\/pub\/reports\/FY2022\/navy\/2022cps.pdf\" target=\"_blank\" rel=\"\"><u>boost-glide<\/u><\/a> hypersonic missiles. CPS uses a two-stage booster to loft a high-altitude glider that can hit a target thousands of miles away in 30 minutes or less. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two Zumwalts have been delivered, and the third is scheduled for 2028. In addition, CPS missiles will arm Virginia-class attack submarines, while the Army uses a land-based version called the <a href=\"https:\/\/www.dote.osd.mil\/Portals\/97\/pub\/reports\/FY2023\/army\/2023lrhw.pdf?ver=jClghaowEkarGt-qUGMXNg%3D%3D\" target=\"_blank\" rel=\"\"><u>Land-Range Hypersonic Weapon<\/u><\/a>. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, modifications to the destroyers \u2014 such as installing hypersonic missiles and vertical launch tubes \u2014 has added costs and delays. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One ship, for example, needed \u201cmore cabling than was anticipated in the initial project design, as the contractor cut and removed more cabling than planned from the forward part of the ship for CPS missile launch tube installation,\u201d GAO noted. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, \u201cthe DDG-1000 class ships have unique systems, such as its radar, combat, and network systems, that are costly and difficult to sustain and maintain,\u201d GAO said. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Zumwalts suffer from unreliable power systems and difficulty in obtaining spare parts. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Despite some <a href=\"https:\/\/www.war.gov\/News\/Releases\/Release\/Article\/4172652\/us-navy-proves-sea-based-hypersonic-launch-approach\/\" target=\"_blank\" rel=\"\"><u>successful<\/u><\/a> flight tests from land facilities, the CPS missile has also run into problems. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The cost of the missiles has risen sharply: a 2020 Navy estimate of $31 billion for 262 missiles has mushroomed into $41 billion for 224 missiles. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cLockheed Martin, the CPS missile body prime contractor responsible for production integration, faces significant production issues that it must address to build the missiles at anticipated rates and costs,\u201d said GAO. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There have been problems with heat-resistant coatings, substandard parts and insufficient production capacity, with the factory only capable of producing six or seven missiles a year instead of the desired 12. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Building the CPS missile has also proved too complex for some workers. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAccording to Navy and Army program officials, the work instructions are largely written as engineering specifications, which the contractor provides to workers who have recently graduated from high school or vocational school,\u201d the GAO report noted. \u201cNavy production oversight officials said that it is unreasonable to expect workers to understand the instructions provided.\u201d <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In theory, the Army should have an easier time with its LRHW missile, which mainly differs from CPS in the launcher. Rather than the cold-gas ejection system that pops CPS from a tube before ignition, LRHW uses a hot-launch system. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, GAO pointed out a concerning lack of coordination between the two services. For example, while the Navy is responsible for production of the missile body, the Army used its own consultant to study how to increase production. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thus, \u201cthe Navy cannot make decisions in isolation since the Army is buying its own missiles and manages key aspects of production,\u201d the report concluded. Without a joint development and procurement strategy, \u201cthe Navy and the Army create the potential for both additional delay and inefficient use of taxpayer funds.\u201d
