Modern missiles make them vulnerable. A $13 billion price tag makes them expensive. New technology may make them unnecessary. June 28 https://www.bloomberg.com/news/articles/2017-06-28/how-america-s-aircraft-carriers-could-become-obsolete
In mundane astrology, the transits of the outermost five major bodies of the solar system — Jupiter, Saturn, Uranus, Neptune, and Pluto – are considered important when the bodies that make up these cycles arrive at significant angular relationships. Jupiter-Pluto form a square [90 degrees] aspect in 2016-17. During this period, there are times when a third faster moving planet triggers the square. Between June 25 and July 2, Mercury and Mars are forming a T with Jupiter-Pluto. One June 25, Mars forms an exact square with Jupiter. A chart for this event at Washington, DC, brings the T-square to an alignment with the meridian axis.
On the IC, Mars [13cn] is conjunct the star Canopus, alpha Argo Navis – the Celestial Ship. It is opposite Pluto [18cp] which in turn is conjunct the stars of the Archer and the Eagle. These figures combine to produce the image depicted above. In a previous post  we have shown how the image is a perfect symbol for a military aircraft. Now if we combine the image of Argo, the Celestial Ship with the Archer and the Eagle do we not have the aircraft carrier!
Pluto rules death and release of the old, outworn, outdated and obsolete in our lives. Its presence in the T-square is signaling the “death” of the aircraft carrier.
