ComNavOps has criticized and mocked the Navy’s headlong, uninformed leap into unmanned vessels and for good reason. The movement is unsupported by realistic experimentation of any type. The odds that uninformed, unsupported actions will lead to a good outcome are very poor. However, the faintest glimmer of hope has emerged from the Navy in the form of some comments by CNO Gilday about the Navy’s unmanned plans.
As you recall, the Navy’s current path is to develop both a large (not very large actually; corvette size) unmanned vessel (LUSV) which will be a mini-arsenal ship and a medium (pretty small actually; patrol boat size) size unmanned vessel (MUSV) which will be a sensor platform. Now, however, CNO Gilday has hinted that plans may change and is backtracking on the MUSV.
I don’t know if we’ll have a medium unmanned or not. The stuff that [Vice Adm. Brad] Cooper’s doing right now with CTF 59 – using small unmanned [vehicles] on the scene in the air to sense the environment … in order to yield a common operational picture for allies and partners, as well as 5th Fleet headquarters, has changed my thinking on the direction of unmanned.[1]
Gilday said the service might be rethinking buying the MUSV after a series of exercises and experiments in U.S. 5th Fleet with Combined Task Force 59 … [1]
Instead of an MUSV,
However, the Navy might be able to get the sensor capability it wanted from MUSV through fused data from networked commercial systems to get an accurate maritime awareness picture more affordably. The 5th fleet started experimenting late last year with a 23-foot Saildrone Explorer out of Jordan and MARTAC’s Mantas T12 USV out of Bahrain.[1]
Did you catch the reference to small, networked commercial systems? This reveals a peacetime mindset – one unhindered by enemy actions or countermeasures. I’ve pointed this out many times in the past. The Navy simply does not appear to believe war with China will actually happen despite having publicly proclaimed that war was highly likely within the next several years. I say they do not believe it because none of their actions show the slightest concern or desire to produce a combat fleet. But, I digress …
Gilday’s comments appear to be a reference to the tiny unmanned sailboats the Navy was playing with (see, “Pointless Drones”). I’ve already mocked the sailboats but using small, cheap, expendable UAVs – though not tiny sailboats - as sensors could be an excellent option and one I’ve suggested many times. If this is what Gilday was suggesting – and it’s far from clear that he was – then the Navy could be on a very good path to developing a viable situational awareness solution.
Still, small UAVs, of whatever type, have significant problems to overcome in order to use them as effective sensor platforms:
- Limited field of view
- Constant communications requirement
- Limited range
- Low survivability
- Requirement for large numbers
Gilday specifically mentioned the small sailboats but he is overlooking some serious problems and limitations with them:
- Seakeeping in open ocean
- Sensor operation in open ocean will see very erratic and fragmented sensor readings due to very low sailboat height operating in waves and troughs
- Very limited sensor range due to very low height; horizon will be around 12 miles which is not much of a field of view relative to the area of the ocean
- Very low speed which requires a very long time to get a sensor boat out to a useful position or to reposition it
Looming over all of the problems is the notion of using commercial unmanned vessels. While this is appealing on the face of it, there is a potential problem with security. Being a commercially developed system, intended for a civilian, commercial market, the controlling software and communications are highly unlikely to be able to withstand the effects of cyber attacks, cyber takeovers, emission controls, jamming, GPS disruption, etc. It is quite likely that an enemy could commandeer these vessels, electronically or via software attacks/hacks with little effort. It is a near certainty that China, and other unfriendly countries, already have the specs and software source code for any product with military potential. They appear to have all our highly protected military information so why would we think they don’t have less secure, civilian information?
As CNO Gilday ponders the future of unmanned based on field experiments, the incriminating question is how come we weren’t conducting these experiments years ago before we jumped into unmanned? We need to use surrogates and develop the concepts first, then the equipment. We’re doing the reverse by developing the equipment first and then the concepts.

The other major question is whether these field experiments are valid or whether they’re scripted exercises designed to produce a desired result … as most military experiments are?
Unmanned assets can be a viable and valuable means of conducting surveillance but only with very strict constraints and only with very specific and well defined concepts of operations. Unfortunately, I see no evidence that we’re following this path. We seem to be grasping every unmanned idea that comes along, hoping something will work. This is why we’re changing our unmanned plans on an almost daily basis.
