Original sentence: (The entire budget for the ATA so far would pay for less than one third of one of the smaller DSN dishes, and about one tenth of the last large radio telescope built in the USA, the Green Bank Telescope.)  Funding issues have forced the exploration of non-astronomical sources, specifically from the US Navy and DARPA, who have multimillion dollar commitments to further the development of such modular arrays in the context of future defense systems.Hence in late 2006, the ATA has become development tool in array technology, as opposed to a fully operational instrument intended first for SETI and then secondarily for astronomy.However, as of October 2006, the ATA-42 is still under construction, with 10 antennas complete and the other 32 in various stages of deployment.In general, the ATA has slipped its projected completion stages, not surprising in an ambitious project with limited funding, reliance on advanced technology, and small margins for dealing with unexpected problems.The ATA was originally planned to be constructed in 4 stages, the ATA-42 (November, 2005), ATA-98 (July, 2006), ATA-206 (April, 2007), and ATA-350 (June, 2008); each number representing the number of dishes in the array at a given time (See Table 1)
Edited sentence: For example, ATA-42 and ATA-98 do not exist, nor will ATA-206 exist in April, 2007.Funding issues have forced the exploraton of non-astronomical sources, specifically from the US Navy and DARPA, who have multimillion dollar commitments to further the development of such modular arrays in the context of future defense systems.Hence in late 2006, the ATA has become a defense development tool, as opposed to a fully operational instrument intended first for SETI and then secondarily for astronomy.However, as of October 2006, the ATA has consistently slipped its projected completion stages, in part due to insufficient funding, lack of readiness of the requisite technology, and thus failed planning.Present capability of the ATA puts it at a low 'technology readiness' value, equivalent to ATA-10 or less in the projected plan.The ATA is planned to be constructed in 4 stages, the ATA-42 (November, 2005), ATA-98 (July, 2006), ATA-206 (April, 2007), and ATA-350 (June, 2008); each number representing the number of dishes in the array at a given time (See Table 1)
