Pentagon Aims to Boost Accuracy of Ballistic Missile Defenses

Technicians prepare a Ground Based Interceptor for emplacement into Missile Field 2 at the Missile Defense Complex at Fort Greely, Alaska, in February 2012. Missile Defense Agency officials want to focus on increasingly the interceptor's accuracy, among other new initiatives.

The Pentagon’s fisc­al 2015 budget re­quest funds new pro­jects aimed at mak­ing U.S. bal­list­ic mis­sile de­fenses more ac­cur­ate and re­li­able, a seni­or of­fi­cial said.

One of three such ini­ti­at­ives is re­design­ing the pivotal Ground Based In­ter­cept­or’s Exoat­mo­spher­ic Kill Vehicle, to the tune of $100 mil­lion in the up­com­ing fisc­al year and $738 mil­lion through fisc­al 2019. The pro­ject is part of the Mis­sile De­fense Agency’s $7.46 bil­lion budget re­quest, un­veiled on Tues­day.

Plans to re­design the prob­lem-plagued kill vehicle fol­low a “long­stand­ing need” for great­er re­li­ab­il­ity of the sys­tem, as evid­enced by sev­er­al in­ter­cept test fail­ures over the past few years, Mis­sile De­fense Agency Dir­ect­or Vice Adm. James Syr­ing told re­port­ers.

The oth­er re­lated ini­ti­at­ives are de­vel­op­ment of a long-range dis­crim­in­at­ing radar for watch­ing over the Pa­cific — pos­sibly from a loc­a­tion in Alaska — and “dis­crim­in­a­tion im­prove­ments” for boost­ing ex­ist­ing home­land de­fenses, Syr­ing said.

Moun­ted atop the Ground Based In­ter­cept­or, the kill vehicle is de­signed to slam in­to in­com­ing mis­siles while in space and keep them from hit­ting U.S. tar­gets.

The term “dis­crim­in­a­tion” in mis­sile de­fense gen­er­ally refers to an in­ter­cept­or’s abil­ity to identi­fy and en­gage in­di­vidu­al tar­gets. Soph­ist­ic­ated bal­list­ic mis­sile at­tacks can in­clude false war­heads or oth­er ob­scur­ants meant to con­fuse de­fens­ive sys­tems. To suc­ceed in knock­ing out in­com­ing at­tacks, in­ter­cept­ors also need an abil­ity to identi­fy and pur­sue tar­gets through any debris cre­ated by pre­vi­ous shots.

The new radar is budgeted at $80 mil­lion in fisc­al 2015, which be­gins Oct. 1, and at $940 mil­lion through the end of the five-year pro­gram plan, ac­cord­ing to an agency spokes­man. Of­fi­cials want $122 mil­lion for dis­crim­in­a­tion im­prove­ments in the next fisc­al year and a total of $198 mil­lion through 2018.

The new in­vest­ments would yield a bal­list­ic mis­sile de­fense ar­chi­tec­ture “cap­able of dis­crim­in­at­ing and killing a re-entry vehicle with a high de­gree of con­fid­ence,” Syr­ing said. The lan­guage not­ably sets the bar high­er for suc­cess­ful per­form­ance than in re­cent years, when of­fi­cials in­stead stressed that the mult­i­bil­lion-dol­lar sys­tem should be ex­pec­ted to of­fer only lim­ited cap­ab­il­ity. They at­trib­uted short­com­ings to a de­cision more than 10 years ago to field a mis­sile de­fense pro­gram in haste.

Mi­chael Gilmore, the Pentagon’s chief weapons test­er, wrote in an an­nu­al over­view of weapon pro­grams in Janu­ary that the failed tests “raise ques­tions re­gard­ing the ro­bust­ness of the EKV’s design” and re­com­men­ded a re­tool­ing.

Ex­actly how the ac­quis­i­tion of a new kill vehicle would un­fold, and wheth­er cur­rent con­tract­or Ray­theon would get the busi­ness, is still an open ques­tion, Re­u­ters re­por­ted on Tues­day.

Mean­while, U.S. of­fi­cials are stick­ing by plans to field 14 ad­di­tion­al Ground-Based In­ter­cept­ors at Fort Greely, Alaska, bring­ing the total num­ber of de­ployed sys­tems to 44 by 2017. The ad­di­tion­al de­ploy­ments, ex­pec­ted to cost $1 bil­lion, are “un­af­fected” by the planned kill-vehicle re­design, ac­cord­ing to Syr­ing.

Byrd Rule Could Trip Up Health Legislation

THE DETAILS

"Even if House Republicans manage to get enough members of their party on board with the latest version of their health care bill, they will face another battle in the Senate: whether the bill complies with the chamber’s arcane ... Byrd rule, which stipulates all provisions in a reconciliation bill must affect federal spending and revenues in a way that is not merely incidental." Democrats should have the advantage in that fight, "unless the Senate pulls another 'nuclear option.'”

The House has passed a one-week spending bill that will avert a government shutdown which was set to begin at midnight. Lawmakers now have an extra week to come to a longer agreement which is expected to fund the government through the end of the fiscal year in September. The legislation now goes to the Senate, where it is expected to pass before President Trump signs it.

THE DETAILS

President Trump’s portrayal of an effort to funnel more Medicaid dollars to Puerto Rico as a "bailout" is complicating negotiations over a continuing resolution on the budget. "House Democrats are now requiring such assistance as a condition for supporting the continuing resolution," a position that the GOP leadership is amenable to. "But Mr. Trump’s apparent skepticism aligns him with conservative House Republicans inclined to view its request as a bailout, leaving the deal a narrow path to passage in Congress."

POTENTIAL GOVERNMENT SHUTDOWN?
Democrats Threaten Spending Bill Over Obamacare

BREAKING

Democrats in the House are threatening to shut down the government if Republicans expedite a vote on a bill to repeal and replace Obamacare, said Democratic House Whip Steny Hoyer Thursday. Lawmakers have introduced a one-week spending bill to give themselves an extra week to reach a long-term funding deal, which seemed poised to pass easily. However, the White House is pressuring House Republicans to take a vote on their Obamacare replacement Friday to give Trump a legislative victory, though it is still not clear that they have the necessary votes to pass the health care bill. This could go down to the wire.
