Lockheed Martin held its first quarter earnings call earlier today. Top company officials hope to "definitize" the LRIP 6 and 7 contracts in the first half of 2013. They're also hoping to secure some cash to start buying long-lead items for LRIP 8--which is expected to consist of 48 jets. A good chunk of those planes are for foreign buyers.
Meanwhile, Lockheed released this video which basically summarizes their 2012 test activities. It's about 15 minutes long.
