First off: This exact story is being reported by many different places, not just Fox News.

Those were some of the results from the first page of google. Reuters and the leftist Guardian both reported the same thing. Claiming some VRW conspiracy about the cost and impact (just because it appeared on FoxNews.com) seems to be jumping to a harsh conclusion about the validity of the arguement.
Relying on any single news source, in this day, is a poor idea to be truly informed. Fox isn't anything special there. Even I read MSNBC and CNN to see what the radical left is thinking day-in-day-out. Lastly on politicalization: it should be noted that many democrats were against this green-fleet 'expansion of the military' when it was introduced under President Bush (just like many Democrats were against the ACA-equivalent proposed by Rep Gingrich in the 90s because they didn't want to force people to pay into for-profit companies). It goes both ways... so the inconsistency argument doesn't really hold much weight because BOTH sides had to have swapped places for the argument to really hold, so both sides are just as culpable. And the devil is in the details - generalizing very complex issues to 'well, you supported something that was kind of similar when you looked at it in the correct light a few years ago' is a pretty lazy arguement.
Second: besides the cost - I would be worried about the weight. I didn't see anything actually accounted for on the loss of energy that there would be by using the less-potent fuel. Even some of the best automobile ethanol-blends available have ~25% less output than the same amount of gas (
quick-read online source and it's also well documented in any flex-fuel owners manual). I understand the desire for our military to be environmentally friendly, but if we were to allow any one-entity to actually do the 'most efficient thing possible' wouldn't we want it to be our warships and planes? Imagine if our warships required 25% more fuel (by way of volume) during WW2? We may have lost the pacific. Fuel was the #1 scarcist commodity for the expeditionary fleet. (A counter to this, that I am aware of - the navy is still using conventional engines, so switching back to conventional fuel during a war wouldn't be a big deal except that we would possibly be lacking the infrastructure to support conventional fuel production.)
Third: I haven't found any counter-evidence to this being cheaper than conventional fuel, even in the long run (except for extreme situations like if we get totally shut off from the rest of the world's oil). If conventional fuel is provided to the government at 3.60/gal that would presumably include the sunk costs comparable to the 26/gal as well. These are contracts just the same (and the risks associated with losing that contract/production after it's expiration, just the same). Even accepting the disparity in sunk cost (presuming that much of the difference is a 1-time cost difference) - to produce enough fuel to meet the navy's needs (even part of their needs), when does the sunk cost actually start to be 'worked out' of the cost? $26/gal for a small fleet for a few weeks... now let's expand that to several large fleets over years. To keep up with production, I don't think the infrastructure cost-savings will be that big of an effect in any near or mid-term projections. To make up for the cost of a biofuel you'd probably be looking at several decades (part of what makes conventional fuels comparably inexpensive is the almost 100 years of infrastructure, right?). Bottom line: some sunk costs will be saved over time, yes, but not enough to account for the 7x cost of traditional fuels.
Also the cost will go down a bit as bulk increases intrinsically, but I have a hard time seeing a decrease to be competitive gal-to-gal (and see above about needing more 'blended-per-mile' than 'gas-per-mile'). Further, this isn't taking into account that OPEC could just increase production, decrease the cost of oil, and remain competitive with any biofuel. This could be an advantage in itself, but that's not the point of this exercise as I don't think the navy is really worried about the cost (which is ultimately the point of the general critique from the GOP).
