In October 2010 the JASDF cancelled work on the RF-15J reconnaissance variant, which would have added optical and infrared cameras and other reconnaissance devices. Japan would continue to use its aging RF-4E reconnaissance planes instead. Toshiba is required to deliver the fighter between September and October 2010 under a series of contracts signed in fiscal 2007 and 2008, totalling 10 billion yen (roughly US$100 million). Failing to procure necessary components from abroad, however, Toshiba had asked the ministry for permission to delay the delivery until spring 2012. The ministry declined the request on the grounds that Toshiba would be unable to deliver the required reconnaissance capabilities in the absence of necessary parts, even with the delay. This decision followed an announcement that Japan was considering buying Global Hawk unmanned aerial vehicles.
