Yes, take a look at the Navy Ocs Nupoc College Programs at the following link and if interested contact a Navy OPO(officer programs officer) sooner rather than later: http://www.cnrc.navy.mil/noru/orojt3/generalofficer.htm
Go to the Contact page at the recruiting district near you to find contact info for the OPO: http://www.navycs.com/districts.html
The Asvab has nothing to do with Navy Ocs. The Astb or at least the Oar section of the Astb.
The Naval Academy is also possible if you will not have reached the 23rd birthday by July 1 of 2012. If you leave this question up I will try and give a fuller answer later tonight. I have to get off YA just now.
Ok, I just read the other question. I was so saddened to hear of your loss. I will try and give as complete an answer as I can. Due to the circumstances, you are now on independent status under fafsa guidelines. http://www.fafsaonline.com/fafsa-form/dependent-status-for-fafsa-5.php
In general this means that if your parents made over $70,000 per year you formerly were not eligible for any federal or state grant type of financial aid, so if you were contemplating leaving school due to financial issues that may not be necessary. If your scholarship is from the universities own sources, you now have a different level of need and there will be no parent contribution so the financial aid office will need to adjust your financial package.
As I understand you are just starting your junior year, if your college has Afrotc, Nrotc, Rotc, any of those are possible as a commissioning source if you extend your undergraduate studies till June 2014 or a combination of graduate and undergraduate studies till at least Jun e 2014. Afrotc, Nrotc, Rotc Scholarships will offset other financial aid in your financial package and also have another effect. The initial active duty service obligation will not accrue potentially very valuable 9/11 GI Bill educational benefits that can be used to finance a graduate or professional education. The same holds for the initial active duty service obligation of service academy commissioned officers and for those who receive Nupoc/Bdcp/Cec benefits.
Nrotc and Naval Academy commissioned Ensigns can generally only choose URL(Unrestricted Line) communities while Navy Ocs commissioned Ensigns can select URL or restricted line and staff communities. http://www.usna.edu/admissions/career.htm
Usafa/Afrotc and West Point/Rotc commissioned 2nd Lieutenants are not similarly restricted in choice of AFSC(Usaf) or Branch(Army.)
This is for West Point and gives an idea of the competition for the various branches. It is similar for Rotc commissioned 2nd Lieutenants. BrADSO means a longer active duty service obligation was agreed to in order to get the desired Branch: http://www.west-point.org/class/usma1979/old/2011_Branch_Results_Summary.pdf
Army Ocs involves enlisting with an Ocs option and first going to enlisted basic followed by Army Ocs. The Army is the only service branch where Ocs Officer Candidates enlist and attend enlisted Basic Training. Branch selection takes place at Ocs according to performance at Ocs. Aviation usually is not available.
Air Force Ots is practically shut down as a commissioning source due to a cutback in the number of Air Force Officers and large Afrotc Classes through at least 2014. Ots serves as a stop gap filling slots still open after Usafa and Afrotc commissioned 2nd Lieutenants are assigned their Afsc.
The Marines PLC is their prime commissioning source. You could do the combined 10 week course next summer or if you extend your graduation through undergrad or graduate education, could do the 6 week Plc Juniors and 6 week Plc Seniors Ocs Courses. One third of Marine Officers are Naval Aviators(pilots.) The choice at the outset is Plc Ground, Plc Naval Aviator, Plc Naval Flight Officer, Plc Law. All Ground Officer Mos are selected at TBS after commissioning and this is regardless of commissioning source including the Naval Academy. The TBS class is split into a Top, Middle and Bottom 1/3. Each 2nd Lt ranks the available Mos and then each Mos is assigned equally from each 1/3 to achieve an equal quality spread among Mos. In other words top of the bottom 1/3 beats everything except top of the top and middle 1/3. All Marine Officer commissioning programs require a 1st class Marine PFT, 225 minimum. Most Oso will not forward an application to a Selection Board with a PFT less than 240. A 280+ is considered competitive for Occ and the Nrotc Marine Option Scholarship.
I am continuing this at the other question since I have hit the ten link maximum.
