During the reign of King Bush II, I wrote about the proposed $400 million new presidential helicopter (March 2008 posting), a pimped-out variant of the standard EH101 that Wikipedia says costs $21 million when customers buy it from Eurocopter/Airbus instead of from Lockheed Martin. It seems that under Barack Obama, the government and its contractors have become more efficient. The new Marine One helicopter will be a tweaked Sikorsky S-92, which have a list price of around $30 million each when they are bought by companies that need to fly out to oil rigs. This press release says that the federal government will get four pimped-out S-92s for only about $300 million each, with options to buy 17 more at an undisclosed (undetermined?) price. The Wikipedia page on the VXX program says that about $1.7 billion was spent on the old plan before it was scrapped and that the projected costs of the old program doubled before it was canceled.
