  • USNS Observation Island (T-AGM-23) was built as the Mariner-class merchant ship Empire State Mariner for the United States Maritime Commission, launched 15 August 1953, and operated by United States Lines upon delivery on 24 February 1954, making voyages for the Military Sea Transportation Service (MSTS) until going into reserve at Mobile, Alabama on 9 November 1954. Title was transferred to the United States Navy on 10 September 1956 and, after conversion, the ship was renamed Observation Island. On commissioning the ship was classified as the "experimental miscellaneous auxiliary" (EAG), USS Observation Island (EAG-154) supporting fleet ballistic missile development. Observation Island was the platform for the first at-sea firing of the Polaris missile in 1959. On 1 April 1968 Observation Island was redesignated as a miscellaneous auxiliary USS Observation Island (AG-154). She was the platform for first at-sea firing of the Poseidon missile in 1969. Observation Island was decommissioned and placed in reserve from 1972 until 1977 in the Suisun Bay Reserve Fleet until withdrawn and then returned in 1978. The ship was permanently withdrawn April 1979 and placed in service with MSTS successor, the Military Sealift Command (MSC). The ship was classified in 1979 as the missile range instrumentation ship USNS Observation Island (T-AGM-23). Observation Island operated worldwide and monitored compliance with strategic arms treaties and supported U.S. military weapons test programs. Observation Island carried the United States Air Force AN/SPQ-11 Cobra Judy passive electronically scanned array radar system for collecting data on missile tests. The ship was operated by MSC for the Air Force Technical Applications Center at Patrick Air Force Base. The ship served the MSC until her inactivation 25 March 2014 after her mission was taken over by USNS Howard O. Lorenzen. (en)

  • La USNS Observation Island (T-AGM-23), ex-MA-28, ex-YAG-57, ex-E-AG-154, ex-Empire State Mariner, è la storica unità della United States Navy che nel 1969 lanciò il primo missile balistico Poseidon, il primo di questo tipo ad essere lanciato da una nave in navigazione, conseguendo il riconoscimento Meritorious Unit Commendation, conferito alla nave e all'equipaggio. La nave è al 2012 una delle due Missile Range Instrumentation Ships (navi con strumentazione per la misura della portata dei missili) impiegata dal Military Sealift Command. Uno dei radar che trasporta è il Cobra Judy . L'unità opera tipicamente nell'Oceano Pacifico, facilmente riconoscibile essendo verniciata totalmente di bianco, apparati elettronici inclusi. Un piccolo ponte da volo è a poppa, ma senza hangar. Tra i sistemi elettronici di bordo, il più notevole è il radar SPG-11 "Cobra Judy", costituito da una antenna piana a dipoli in fase, capace di seguire a lungo raggio bersagli multipli ad altissime velocità, come per l'appunto le testate multiple dei missili in fase di rientro nell'atmosfera. La struttura entro cui è sistemato il radar ha forma tronco-piramidale e pesa in tutto oltre 250 tonnellate. La dotazione di sistemi elettronici di comunicazione comprende un paio di grandi antenne satellitari per la comunicazione in tempo reale dei dati ottenuti, sistemate sul grande blocco di sovrastrutture a centro nave, davanti al fumaiolo.
