1st time Livery install into DCS WORLD:

Open Windows File Explorer Win + E

go to C: Users (click it open)

Find your User Name: (Example) Tobby (click it open)

Look for the DCS install folder (click it open)

IF YOU HAVE NEVER INSTALLED LIVERIES: (Do This)

Create a NEW folder and spell it exactly like this: Liveries

INSIDE THE FOLDER Liveries

Create a NEW folder and spell it exactly like this: ticonderog

NOW FOR THE END

Open this Zip file and extract all file folders 
into this last folder you just named: ticonderog

The pathe should now look like C:\Users\"Your username"\Saved Games\DCS\Liveries\ticonderog\ GAME FILE SKINS ARE HERE

If you did this correctly and you know how to use the DCS Mission Editor
And you know how to add a Ship the change it's Skin then you will find my
2 new skins to use called USCG_Ticonderoga_60_Dirty and USCG_Ticonderoga_69_Clean
Dirty need new paint has heavy hard use
Clean is a little bit better
Now go land your Huey on one.

Give each one a Radio Freq. AM Remember it you will need it.
If you know how to use the UHF radio turn it on set the channel to the
Freq you gave the ship. Set your Intercom selector to 2 hit your Set Key shortcut button to open up the RADIO MENU.
Find the Name of the Ship click on it when you are near it and hit Inbound.
The Landing pad fence will drop away for your landing.
Try not to kill yourself. The above is not a step by step how to: So Learn the S.O.P. for how to do this.
Good Luck.
