This is a good find. However I read through the key portions of the cited Lukasik article about the founding of ARPANET (pp. 10-12), and I can't find any real support for the claim in his introduction. He mentions the Baran RAND proposal and its survivability goals, but I saw no evidence provided that ARPA funded Taylor's ARPANET project because they thought it would help meet those same goals.

It's also important to mention that Lukasik wrote this article in 2011, over 40 years after the fact, and that the claim you quote is contradicted by pretty much everyone else involved at the time, including Lukasik's boss at the time ARPANET was conceived, Charles Herzfeld (as cited in the same wikipedia article.)
